Question

To repair body damage on a car auto body charges $125 plus $18 per hour car care charges $200 plus $12 per hour determine the number of hours for which the two body shops will cost the same

Answer 1

First of all, the equation is 125+18x=200+12x.
First subtract 12x from both sides of the equation. Your equation will now look like this:
125+30x=200
Subtract 125 from each side of the equation.
30x=75
Divide both sides by 30.
x= 2.5
Therefore, the answer is hours.
Hope this helps!
