Answer:
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '12x' to each side of the equation.
-15 + -15x + 12x = -12x + 12x
Combine like terms: -15x + 12x = -3x
-15 + -3x = -12x + 12x
Combine like terms: -12x + 12x = 0
-15 + -3x = 0
Add '15' to each side of the equation.
-15 + 15 + -3x = 0 + 15
Combine like terms: -15 + 15 = 0
0 + -3x = 0 + 15
-3x = 0 + 15
Combine like terms: 0 + 15 = 15
-3x = 15
Divide each side by '-3'.
x = -5
Simplifying
x = -5 so the answer is x=5(56+)_-2 pls give me brainlyest
