-\frac{1}{4}x-3=y
Swap sides so that all variable terms are on the left hand side.
-\frac{1}{4}x=y+3
Add 3 to both sides.
\frac{-\frac{1}{4}x}{-\frac{1}{4}}=\frac{y+3}{-\frac{1}{4}}
Multiply both sides by -4.
x=\frac{y+3}{-\frac{1}{4}}
Dividing by -\frac{1}{4} undoes the multiplication by -\frac{1}{4}.
x=-4y-12
Divide y+3 by -\frac{1}{4} by multiplying y+3 by the reciprocal of -\frac{1}{4}.
