Answer:

15x - 2

Step-by-step explanation:

Since there is an addition sign in between the parentheses, just ignore the parentheses all together.  You can't combine anything inside the parentheses anyways.  

New expression:

12x + 5 + 3x - 7

Combine like terms.

12x + 3x = 15x           5 - 7 = -2

Answer:

15x - 2
