\sqrt{12-4x}=y
Swap sides so that all variable terms are on the left hand side.
-4x+12=y^{2}
Square both sides of the equation.
-4x+12-12=y^{2}-12
Subtract 12 from both sides of the equation.
-4x=y^{2}-12
Subtracting 12 from itself leaves 0.
\frac{-4x}{-4}=\frac{y^{2}-12}{-4}
Divide both sides by -4.
x=\frac{y^{2}-12}{-4}
Dividing by -4 undoes the multiplication by -4.
x=-\frac{y^{2}}{4}+3
Divide y^{2}-12 by -4.
