15-0.25x=0
Swap sides so that all variable terms are on the left hand side.
-0.25x=-15
Subtract 15 from both sides. Anything subtracted from zero gives its negation.
x=\frac{-15}{-0.25}
Divide both sides by -0.25.
x=\frac{-1500}{-25}
Expand \frac{-15}{-0.25} by multiplying both numerator and the denominator by 100.
x=60
Divide -1500 by -25 to get 60.
