Question

Misha solves the equation 3 x minus 2 (x + 3) = 4 (x minus 2) minus 7 by applying the distributive property to each side of the equation. The result is 3 x minus 2 x minus 6 = 4 x minus 8 minus 7. Misha then wants to combine like terms. Which are the terms Misha should combine?
3x – 2x and –8 – 7
3x – 2x and 8 – 7
3x – 2x + 4x and –6 – 8 – 7
3x – 2x – 6 and 4x – 8 – 7

Answer 1

3x – 2x and –8 – 7.

Combining gives: (3x − 2x) − 6 = 4x + (−8 − 7) → x − 6 = 4x − 15.
