The question, in short
Solve two linear equations: 8x + 7 = 39 and 2(5y − 1) = 24, finding the value of each variable.
Summarised in our own words. Use the official paper for the exact wording and any diagrams.
Part (a) · 2 marks
Solve 8x + 7 = 39 for x.
- 18x = 39 − 7 = 32
- 2x = 4
Answer4
Part (b) · 3 marks
Solve 2(5y − 1) = 24 for y.
- 15y − 1 = 24 ÷ 2 = 12
- 25y = 13
- 3y = 13/5 = 2.6
Answer2.6 or 13/5
