Step-by-step explanation:
In step 2, the result of eliminating parentheses is shown. That is done by using the distributive property to multiply -2 by each of the terms inside parentheses, giving ...
(-2)(x) +(-2)(12) = -2x -24
In step 3, 2x is added to both sides of the equation. This eliminates the -2x term on the right, and increases the -6x term on the left to -4x.
In step 4, the equation is divided by -4. This makes the coefficient of x become 1.
