Worked Example
Applied word problem 8
For Class 10 Mathematics, explain or solve a substitution method question from the chapter "Pair of Linear Equations in Two Variables". Focus on applied word problem and show the working clearly.
Step-by-step solution path
- Read the topic idea: Substitution Method.
- Recall the core explanation from the chapter: Methods of solving two linear equations using graphical and algebraic approaches.
- Use the related formula "Infinite Solutions Condition" 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 Substitution Method. A strong solution should identify the correct data, apply Infinite Solutions Condition, and explain each transition instead of jumping directly to the answer.
