Check my working on this maths problem.

Problem: [paste]
My working: [paste]
Level: [details]

Ask me up to 3 short questions first if anything important is missing. Wait for my answers.

Then:
1. Whether the final answer is right.
2. The first wrong step, if any.
3. A corrected path from there.
4. A similar practice question.

Only use what I've told you, leave blanks for anything I haven't given, and don't invent facts, steps or official URLs you're not sure of. UK English.

Stay in this ChatGPT chat. Do not turn on apps or connectors, and do not use memory from another chat.
