Hector works 12 hours per week at a part time job. His original pay rate was $8 per hour, but he recently received a raise of x

Olegator [25]

Answer:

x = $\frac{8}{3}$

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

128=12(8+x)

128=(12)(8)+(12)(x)(Distribute)

128=96+12x

128=12x+96

Step 2: Flip the equation.

12x+96=128

Step 3: Subtract 96 from both sides.

12x+96−96=128−96

12x=32

Step 4: Divide both sides by 12.

$\frac{12x}{12} =\frac{32}{12}$

x=8/3
