Answer:
Simplifying
3x + -124 + -12x = 128
Reorder the terms:
-124 + 3x + -12x = 128
Combine like terms: 3x + -12x = -9x
-124 + -9x = 128
Solving
-124 + -9x = 128
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '124' to each side of the equation.
-124 + 124 + -9x = 128 + 124
Combine like terms: -124 + 124 = 0
0 + -9x = 128 + 124
-9x = 128 + 124
Combine like terms: 128 + 124 = 252
-9x = 252
Divide each side by '-9'.
x = -28
Simplifying
x = -28
