Algebra practice question

Answer: 5

Let the number be x: 4(x − 3) = 8. Divide by 4: x − 3 = 2, so x = 5.

Common wrong answers

If you answered 2

2 is x − 3, one step short.

If you answered 11

11 comes from 4x − 3 = 8 — the 4 must multiply the whole difference, including the 3.

If you answered 1.25

1.25 is 5/4, dividing the answer by 4 again.
