4000=40x-500
Combine 25x and 15x to get 40x.
40x-500=4000
Swap sides so that all variable terms are on the left hand side.
40x=4000+500
Add 500 to both sides.
40x=4500
Add 4000 and 500 to get 4500.
x=\frac{4500}{40}
Divide both sides by 40.
x=\frac{225}{2}
Reduce the fraction \frac{4500}{40} to lowest terms by extracting and canceling out 20.
