Basic Algebra MCQs from the FAST-pattern papers
Try each one before opening the answer. Each comes with a short explanation.
- Q1 · FAST Past Paper 07 · Basic Algebra
If 3(x − 2) = 2x + 5, then x is equal to:
- A.11
- B.−1
- C.7
- D.3
Show answer
Answer: A. 11 — 3x − 6 = 2x + 5, so x = 11.
- Q2 · FAST Past Paper 06 · Basic Algebra
If (x + 4)/3 = (x − 2)/2, then x is:
- A.−14
- B.14
- C.2
- D.10
Show answer
Answer: B. 14 — Cross-multiply: 2x + 8 = 3x − 6, so x = 14.

If 5x − 7 = 3x + 9, then x is equal to:
- A.1
- B.8
- C.16
- D.−8
Show answer
Answer: B. 8 — 2x = 16, so x = 8.
