-7x=36-4y
Swap sides so that all variable terms are on the left hand side.
\frac{-7x}{-7}=\frac{36-4y}{-7}
Divide both sides by -7.
x=\frac{36-4y}{-7}
Dividing by -7 undoes the multiplication by -7.
x=\frac{4y-36}{7}
Divide 36-4y by -7.
-4y=-7x-36
Subtract 36 from both sides.
\frac{-4y}{-4}=\frac{-7x-36}{-4}
Divide both sides by -4.
y=\frac{-7x-36}{-4}
Dividing by -4 undoes the multiplication by -4.
y=\frac{7x}{4}+9
Divide -7x-36 by -4.
