Set up a proportion and solve it to demonstrate this type of business application. (An example might be 5 hours / $20 = 10 hours / x). Your post should include all the steps involved in solving for your variable and explanations where needed (introducing your proportion and what it represents and an explanation of the solution.). Remember that setting the cross products (multiplications) equal, and then solving for x is the way to solve a proportion.

Step-by-step explanation:

The problem could be

A person earns $20 for working 5 hours.

How much will a person earn if they work 10 hours?

using proportion

Multiply in cross

divide by 5 both sides

37/3

step-by-step explanation:

step 1: simplify both sides of the equation.

7x+8(x+

1

4

)=3(6x−9)−8

7x+(8)(x)+(8)(

1

4

)=(3)(6x)+(3)(−9)+−8(distribute)

7x+8x+2=18x+−27+−8

(7x+8x)+(2)=(18x)+(−27+−8)(combine like terms)

15x+2=18x+−35

15x+2=18x−35

tep 2: subtract 18x from both sides.

15x+2−18x=18x−35−18x

−3x+2=−35

step 3: subtract 2 from both sides.

−3x+2−2=−35−2

−3x=−37

step 4: divide both sides by -3.

−3x

−3
