assume

substitute

Answer: x=5
Simplifying
5(x + -2) = 15
Reorder the terms:
5(-2 + x) = 15
(-2 * 5 + x * 5) = 15
(-10 + 5x) = 15
Solving
-10 + 5x = 15
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '10' to each side of the equation.
-10 + 10 + 5x = 15 + 10
Combine like terms: -10 + 10 = 0
0 + 5x = 15 + 10
5x = 15 + 10
Combine like terms: 15 + 10 = 25
5x = 25
Divide each side by '5'.
x = 5
Simplifying
x = 5
