By rearranging your terms! 

1) First, remove the parentheses. 
2x+5+3x-12

2) Next rearrange like terms together
2x+3x+5+(-12)

3) Now combine like terms!
2x+3x= 5x
5 +(-12)= -7 

4) Final answer: 5x+(-7)

Simplifying
2x + 5 + -3x = 12

Reorder the terms:
5 + 2x + -3x = 12

Combine like terms: 2x + -3x = -1x
5 + -1x = 12

Solving
5 + -1x = 12

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

 Add '-5' to each side of the equation.
5 + -5 + -1x = 12 + -5

 Combine like terms: 5 + -5 = 0
0 + -1x = 12 + -5
-1x = 12 + -5

 Combine like terms: 12 + -5 = 7
-1x = 7
  Divide each side by '-1'.
x = -7

 
Simplifying
x = -7
