8-49.
1. Solve these equations for x. Check your answers. Homework Help ✎

1. 2(x + 4.5) = 32

2. 6 + 2.5x = 21

3. =

Distribute.

2(x) + 2(4.5) = 32

2x + 9 = 32
−9 −9
2x = 23

Subtract 9 from both sides.

Divide by 2.

$\frac{2\textit{x}}{2}=\frac{23}{2}$

x = 11.5

x = 6

Multiply both sides by 9 and by 16.
