640=15800+35x+20x
Multiply both sides of the equation by 20.
640=15800+55x
Combine 35x and 20x to get 55x.
15800+55x=640
Swap sides so that all variable terms are on the left hand side.
55x=640-15800
Subtract 15800 from both sides.
55x=-15160
Subtract 15800 from 640 to get -15160.
x=\frac{-15160}{55}
Divide both sides by 55.
x=-\frac{3032}{11}
Reduce the fraction \frac{-15160}{55} to lowest terms by extracting and canceling out 5.
