-0.3x+0.4-0.2x=-1.6
Subtract 0.2x from both sides.
-0.5x+0.4=-1.6
Combine -0.3x and -0.2x to get -0.5x.
-0.5x=-1.6-0.4
Subtract 0.4 from both sides.
-0.5x=-2
Subtract 0.4 from -1.6 to get -2.
x=\frac{-2}{-0.5}
Divide both sides by -0.5.
x=\frac{-20}{-5}
Expand \frac{-2}{-0.5} by multiplying both numerator and the denominator by 10.
x=4
Divide -20 by -5 to get 4.
