-0.2x+720=70
Combine 1.6x and -1.8x to get -0.2x.
-0.2x=70-720
Subtract 720 from both sides.
-0.2x=-650
Subtract 720 from 70 to get -650.
x=\frac{-650}{-0.2}
Divide both sides by -0.2.
x=\frac{-6500}{-2}
Expand \frac{-650}{-0.2} by multiplying both numerator and the denominator by 10.
x=3250
Divide -6500 by -2 to get 3250.
