y^{2}-16=-2\left(x-3\right)
Calculate 4 to the power of 2 and get 16.
y^{2}-16=-2x+6
Use the distributive property to multiply -2 by x-3.
-2x+6=y^{2}-16
Swap sides so that all variable terms are on the left hand side.
-2x=y^{2}-16-6
Subtract 6 from both sides.
-2x=y^{2}-22
Subtract 6 from -16 to get -22.
\frac{-2x}{-2}=\frac{y^{2}-22}{-2}
Divide both sides by -2.
x=\frac{y^{2}-22}{-2}
Dividing by -2 undoes the multiplication by -2.
x=-\frac{y^{2}}{2}+11
Divide y^{2}-22 by -2.
