Algebra practice question

Answer: 9

Distribute: 7x − 4x − 8 = 19 → 3x = 27 → x = 9.

Common wrong answers

If you answered 7

7 comes from 7x − 4x + 2 = 19 (distributing the 4 to only the x).

If you answered 27

27 is 3x, before dividing by 3.

If you answered 3.67

3.67 comes from 3x = 11, subtracting 8 instead of adding it.
