Worked Example
Revision challenge 9
For Class 7 Mathematics, explain or solve a solving by transposition question from the chapter "Simple Equations". Focus on revision challenge and show the working clearly.
Step-by-step solution path
- Read the topic idea: Solving by Transposition.
- Recall the core explanation from the chapter: Setting up and solving linear equations in one variable using transposition.
- Use the related formula "Check Solution" as the main tool while solving.
- Write the reasoning in simple school-level language before the final answer.
Final learning answer
This example is centred on Solving by Transposition. A strong solution should identify the correct data, apply Check Solution, and explain each transition instead of jumping directly to the answer.
