Algebra practice question
Twice the result of subtracting 5 from three times a number is 32. What is the number?
Answer: 7
2(3n − 5) = 32 gives 3n − 5 = 16, so n = 7.
Common wrong answers
- If you answered 9
- 9 solves 3n − 5 = 22.
- If you answered 16
- 16 is 3n − 5.
- If you answered 12.33
- 12.33 solves 6n − 5 = 32, not distributing the 2 to the 5.
