Answer:

x = 2

Step-by-step explanation:

We can make an equation that meets the requirements stated.

Decreased signifies subtraction, so 12 will reduce the value after it. A number can be any letter you'd like, but I'll stick to x. Since 2 is multiplying that number, we can make 2 the coefficient. Finally, set it equal to 8.

12 - 2x = 8 Subtract 12 from both sides of the equation.

-2x = -4 Divide by -2 on both sides of the equation.

x = 2

Chad makes $10 per yard, and he makes 3 yards

3 x 10 = 30

Chad makes $5 per hour, and he works 8 hours

5 x 8 = 40

30 + 40 = 70

Chad makes $70 in all
