Question

What is the reason for each step in the solution of the equation?
-8 (x + 5) = 12x

Answer 1

Given

Distributive

Addition

Division

Explanation:

-8(x - 5) = 12x

Multiply -8 by the x and by the 5 to get:

-8x + 40 = 12x

Add 8x to both sides to get:

40 = 20x

The norm is to turn that around to:

20x = 40

Divide both sides by 20 to get x by itself:

x = 2
