Algebra practice question

Answer: 7

3x + 6 = 5x − 4 → 10 = 2x → x = 5. Then x + 2 = 7.

Common wrong answers

If you answered 3

3 comes from x = 1 (2x = 2, a sign slip) plus 2.

If you answered 5

5 is x, but the question asks for x + 2.

If you answered 21

21 is 3(x + 2), the left side's value.
