Algebra practice question
What value of x satisfies 3(2x − 1) = 4x + 11?
Answer: 7
Distribute: 6x − 3 = 4x + 11. Then 2x = 14, x = 7.
Common wrong answers
- If you answered 4
- 4 comes from 2x = 8, subtracting 3 from 11 instead of adding it.
- If you answered 6
- 6 comes from 6x − 1 = 4x + 11, forgetting to distribute the 3 to the −1.
- If you answered 1.4
- 1.4 comes from 10x = 14, adding 4x instead of subtracting.
