1200=3x+5500x+70
Multiply both sides of the equation by 100.
1200=5503x+70
Combine 3x and 5500x to get 5503x.
5503x+70=1200
Swap sides so that all variable terms are on the left hand side.
5503x=1200-70
Subtract 70 from both sides.
5503x=1130
Subtract 70 from 1200 to get 1130.
x=\frac{1130}{5503}
Divide both sides by 5503.
