Algebra practice question
If 6 − (x − 4)/2 = 1, what is the value of x?
Answer: 14
(x − 4)/2 = 5 → x − 4 = 10 → x = 14.
Common wrong answers
- If you answered 6
- 6 comes from (x − 4)/2 = 1, dropping the 6.
- If you answered 9
- 9 comes from x − 4 = 5, forgetting to multiply by 2.
- If you answered -6
- −6 comes from (x − 4)/2 = −5, a sign slip.
