Answer:
43
Explanation:
Simplifying
3x + -36 + 32 + x + 12 = 180
Reorder the terms:
-36 + 32 + 12 + 3x + x = 180
Combine like terms: -36 + 32 = -4
-4 + 12 + 3x + x = 180
Combine like terms: -4 + 12 = 8
8 + 3x + x = 180
Combine like terms: 3x + x = 4x
8 + 4x = 180
Solving
8 + 4x = 180
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-8' to each side of the equation.
8 + -8 + 4x = 180 + -8
Combine like terms: 8 + -8 = 0
0 + 4x = 180 + -8
4x = 180 + -8
Combine like terms: 180 + -8 = 172
4x = 172
Divide each side by '4'.
x = 43
Simplifying
x = 43
