0.3x+15-0.6x=0
Subtract 0.6x from both sides.
-0.3x+15=0
Combine 0.3x and -0.6x to get -0.3x.
-0.3x=-15
Subtract 15 from both sides. Anything subtracted from zero gives its negation.
x=\frac{-15}{-0.3}
Divide both sides by -0.3.
x=\frac{-150}{-3}
Expand \frac{-15}{-0.3} by multiplying both numerator and the denominator by 10.
x=50
Divide -150 by -3 to get 50.
