8-68.

Show the “check” for each of the problems below. Write whether the solution is correct or incorrect.

1. For $3x + 2 = x − 2$, does $x = 0$?

Substitute $0$ for $x$.

$3 \left(0\right) + 2 = \left(0\right) − 2$
Now simplify.

$0 + 2 = 0 − 2$

$2 = −2$

Is this statement true?

2. For $3\left(x − 2\right) = 30 + x − 2 − x + 2$, does $x = 12$?

Follow the steps in part (a).
