Advanced Math practice question

Answer: -7

x − 3 = 2(x + 2) gives x − 3 = 2x + 4, so x = −7.

Common wrong answers

If you answered 1

1 comes from setting the numerator equal to 2x.

If you answered 7

7 has the sign wrong.

If you answered -1

−1 comes from x − 3 = 2x + 2, not distributing the 2 over the +2.
