Answer:
-12
Step-by-step explanation:
Reorder the terms:
15 + 5x = -45
Solving
15 + 5x = -45
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-15' to each side of the equation.
15 + -15 + 5x = -45 + -15
Combine like terms: 15 + -15 = 0
0 + 5x = -45 + -15
5x = -45 + -15
Combine like terms: -45 + -15 = -60
5x = -60
Divide each side by '5'.
x = -12 :)
