The question, in short
Two line segments have lengths 10x − 12 and 2x + 3, with the first three times the second; form an equation and solve for x.
Summarised in our own words. Use the official paper for the exact wording and any diagrams.
Solution · 4 marks
- 110x − 12 = 3(2x + 3)
- 210x − 12 = 6x + 9
- 310x − 6x = 9 + 12
- 44x = 21
- 5x = 5.25
