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.
