50+0.3x-0.5x=10
Subtract 0.5x from both sides.
50-0.2x=10
Combine 0.3x and -0.5x to get -0.2x.
-0.2x=10-50
Subtract 50 from both sides.
-0.2x=-40
Subtract 50 from 10 to get -40.
x=\frac{-40}{-0.2}
Divide both sides by -0.2.
x=\frac{-400}{-2}
Expand \frac{-40}{-0.2} by multiplying both numerator and the denominator by 10.
x=200
Divide -400 by -2 to get 200.
