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

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

   Hint (a):

   Substitute $0$ for $x$.

   More Help (a):

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

   More Help:

   $0 + 2 = 0 − 2$
   
   $2 = −2$
   
   Is this statement true?

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

   Hint (b):

   Follow the steps in part (a).
