3-107.

Solve each equation. Homework Help ✎

Distribute the 3 over the parentheses.

3(*x*) − 3(2) = −6

3*x*− 6 = −6Add 6 to both sides.

3*x*− 6 + 6 = −6 + 6

3*x*= 0

Divide both sides by 3.

3*x*÷ 3 = 0 ÷ 3*x*= 0

Simplify both sides.

2*x*+ 2 + 3 = 3*x*− 3

2*x*+ 5 = 3*x*− 3Add 3 to both sides leave only one constant.

2*x*+ 5 + 3 = 3*x*− 3 + 3

2*x*+ 8 = 3*x*

Then take 2*x*from both sides to isolate*x*.

2*x*+ 8 −2*x*= 3*x*− 2*x**x*= 8

Start by using generic rectangles to rewrite both sides without parentheses. Then solve using the same method as (b).
