600-0.25x=y
Swap sides so that all variable terms are on the left hand side.
-0.25x=y-600
Subtract 600 from both sides.
\frac{-0.25x}{-0.25}=\frac{y-600}{-0.25}
Multiply both sides by -4.
x=\frac{y-600}{-0.25}
Dividing by -0.25 undoes the multiplication by -0.25.
x=2400-4y
Divide y-600 by -0.25 by multiplying y-600 by the reciprocal of -0.25.
