y^{2}-10x-8y+32=y^{2}
Add y^{2} to both sides. Anything plus zero gives itself.
-10x-8y+32=y^{2}-y^{2}
Subtract y^{2} from both sides.
-10x-8y+32=0
Combine y^{2} and -y^{2} to get 0.
-10x+32=8y
Add 8y to both sides. Anything plus zero gives itself.
-10x=8y-32
Subtract 32 from both sides.
\frac{-10x}{-10}=\frac{8y-32}{-10}
Divide both sides by -10.
x=\frac{8y-32}{-10}
Dividing by -10 undoes the multiplication by -10.
x=\frac{16-4y}{5}
Divide -32+8y by -10.
-10x-8y+32=0
Combine -y^{2} and y^{2} to get 0.
-8y+32=10x
Add 10x to both sides. Anything plus zero gives itself.
-8y=10x-32
Subtract 32 from both sides.
\frac{-8y}{-8}=\frac{10x-32}{-8}
Divide both sides by -8.
y=\frac{10x-32}{-8}
Dividing by -8 undoes the multiplication by -8.
y=-\frac{5x}{4}+4
Divide 10x-32 by -8.
