Is this an equation?
What are you to do?
If you are to evaluate it, first clear the parentheses.
0.5(12z-7)-3.5z+3.5
6z-3.5-3.5z+3.5
The two z terms add to 2.5z
The two numbers evaluate to zero.
If you had shown your work we could tell you where you went wrong.

0.5(12z-7)-3.5z+3.5
6z - 3.5 - 3.5z + 3.5
6z - 3.5z = 2.5z
6z - 3.5 - 3.5z + 3.5
6z - 3.5z = 2.5z
