Linear Equations with Brackets
Solve for x: 3(x − 2) + 5 = 20
SparkHi! I’m Spark, your AI study partner. We’re looking at 3(x − 2) + 5 = 20. Before we touch the x inside the bracket, what’s your first move to simplify the left side?
These are the free session’s own scripted replies. The session itself adds the whiteboard, all five hints and voice.
Anyone can get the answer now.Spark helps you get to it.
Same question, two helpers
One gives you x = 7. One gives you the method.
Scroll and watch them answer. The answer bot is done at once. Spark takes longer, because you do the writing.
An answer bot
- Solve 3(x − 2) + 5 = 20
- 3(x − 2) + 5 = 20 3(x − 2) = 15 x − 2 = 5 x = 7 Answer: x = 7
- ok thanks
Copied in ten seconds. Tomorrow’s test asks 4(x + 1) − 3 = 17, and it is a blank again.
Spark
- Solve 3(x − 2) + 5 = 20
- What is sitting outside the bracket that you could clear first?
- The + 5. Take 5 from both sides: 3(x − 2) = 15
- Yes. Now, how do you undo the × 3?
- Divide by 3, so x − 2 = 5, and x = 7
- Check it yourself: put 7 back into the first line. Does it give 20?
You wrote every line, so tomorrow’s question is the same three moves.

How a session goes
Five hints. You write every line.
One real problem, worked the Spark way. Scroll and watch each hint arrive only when it is needed.
Your whiteboard
2(x − 3) = 10
- I need to find x
- 2x − 6 = 10
- 2x = 16
- x = 8
- 2(8 − 3) = 10
Hint 5 · Check your own stepPut 8 back into the first line. Does it hold?
- Hint 1 of 5 · Spot the goal
“What is this equation asking you to find?”
Spark starts with what you notice, not with a method. You write down what you are solving for.
- Hint 2 of 5 · Name the idea
“The 2 multiplies everything in the brackets. What do you get if you share it out?”
Still stuck? The next hint names the idea you need. You do the expanding yourself.
- Hint 3 of 5 · Focus the next move
“What could you add to both sides so the 6 disappears?”
One focused question points at the next move without making it for you.
- Hint 4 of 5 · Try a twin
“Here is a twin: 3y = 12 becomes y = 4. What did that last step do?”
When you are really stuck, Spark works a similar problem with different numbers. Your problem stays yours.
- Hint 5 of 5 · Check your own step
“Put 8 back into the first line. Does it hold?”
You check the answer yourself. When it holds, the line turns green and your skill bar moves for the steps you verified.
Inside a session
Work the way you already work.
Draw it, say it, or snap your worksheet. Spark reads all of it.
Talk it through
Hold the mic and think out loud. Spark answers aloud, and stops the moment you press again.
Bring your school worksheet
Upload the PDF or snap a photo of your working. Spark quotes the page and checks the line you are stuck on.
See every skill move
Each subject splits into small skills. Bars move when you verify steps yourself, and a linked parent sees a calm summary.
How it compares
Help that leaves the thinking to you.
Most help is built to get you to the answer. Spark is built to get you to the next step.
| Spark | Private tutor | Answer app | General AI chatbot | |
|---|---|---|---|---|
| Hands you the final answer | Never, even if you ask | Depends on the tutor | Yes, that is the point | Usually, if you ask |
| There at 11pm before a test | Yes | Only at booked times | Yes | Yes |
| Reads your own working | Whiteboard ink and photos | Yes, in person | The question, not your working | If you upload it |
| Knows which skill is holding you back | A bar for every syllabus skill | If they keep notes | No | No |

| Cost | Free while we test | Paid by the hour | Often a subscription | Free or a subscription |
A general picture of each kind of help, not a review of any one product. A good tutor does a lot of what Spark does; Spark is there at the hours a tutor is not.
The promise
What Spark will and won’t do
Spark will
- Ask what you have already tried, and wait for an answer.
- Point at the exact step where the reasoning breaks, without repairing it.
- Name the first move or rule for a step, then wait for you to write and carry out the step yourself.
- Work a similar example with different numbers when you are genuinely stuck.
- Tell you plainly when a step is wrong, and say which step it was.
- Say it is an AI — every session, including when it is being encouraging.
Spark won’t
- Give the final answer or a finished solution, even when you ask for it directly.
- Do your homework for you. It helps you do it, which is slower and worth more.
- Help with a graded test or a live exam. It offers to practise the same topic afterwards instead.
- Pretend to be a person, or to know your teacher, your class or your textbook.
- Invent a fact to keep the conversation going. It will say when it is not sure.
- Give medical, legal or personal advice.
AI can still make mistakes, so check against your notes and your teacher’s marking. Safety and privacy →
For parents
See the progress, not just the homework.
Link your account with a code from your child, and read how each session went. You can see everything and change nothing.
You see the learning, not just the homework
Mastery for each subject, a short summary of every recent session, and the full transcript when you want to read how a step was reached.
Linked by a code your child gives you
Your child makes a six-character code on their Progress page and hands it to you. No account is found by guessing an email address.
Read-only, by design
You can read everything and change nothing. A parent cannot write in a session or edit a record, and that is enforced in the database too.
Flags you can count
Every reply that needed review is counted, with answer-leak flags and safety flags kept apart, so you see the number rather than a reassurance.
No audio kept, ever
Voice is turned into text once and the recording is thrown away. The transcript stays, because it is the lesson record.

Questions
Questions from students and parents
What is the tutor’s name, and how does it help without spoiling answers?
Meet Spark, your Socratic AI study partner. Instead of handing over a finished homework answer to copy, Spark checks what you have tried so far on the shared whiteboard, spots the exact line where a step breaks, and offers up to five hints, one at a time, so you reach the solution yourself.
Can I try a session right now without an account?
Yes. Choose “Try a free session” anywhere on the site, or go to /try. You can draw on the whiteboard, ask for hints, try voice, or type your own question without an account.
Can I upload a school worksheet PDF or a photo of my handwritten working?
Yes. You can drop in a school worksheet PDF (which Spark reads page by page), snap a photo of your handwritten working, speak with push-to-talk voice, or sketch on the shared whiteboard.
How do the hints and skill bars work?
Every problem has up to five hints, and each gives a little more: first what you notice, then the idea you need, then a focused question, then a similar problem with different numbers, and last a nudge to check your own final step. Your skill bar moves when you verify steps yourself, weighted by how many hints you needed.
What can a linked parent or guardian see?
You can generate a one-time 6-character code from your dashboard to link a parent account. Linked parents get a calm, read-only summary of your topic mastery, recent session takeaways, and any safety notices.
Bring the question you are stuck on.
