9-20.

Simplify and solve each equation below for

*x*. Show your work and check your answer. Homework Help ✎24 = 3

*x*+ 32(

*x*– 6) =*x*– 143(2

*x*– 3) = 4*x*– 5

Begin isolating *x* by subtracting 3 from both sides.

−3 + 24 = 3*x* + 3 − 3

21 = 3*x*

Divide both sides by 3.

*x* = 7

Follow the methods presented in (a) and (b).

Begin by distributing.

2(*x*) − 2(6) = *x* − 14

2*x* − 12 = *x* − 14

Add 12 to both sides.

2*x* = *x* − 2

Subtract *x* from each side.

*x* = −2

Follow the methods presented in (a) and (b).
