4x=-36-4y
Subtract 4y from both sides.
4x=-4y-36
The equation is in standard form.
\frac{4x}{4}=\frac{-4y-36}{4}
Divide both sides by 4.
x=\frac{-4y-36}{4}
Dividing by 4 undoes the multiplication by 4.
x=-y-9
Divide -36-4y by 4.
4y=-36-4x
Subtract 4x from both sides.
4y=-4x-36
The equation is in standard form.
\frac{4y}{4}=\frac{-4x-36}{4}
Divide both sides by 4.
y=\frac{-4x-36}{4}
Dividing by 4 undoes the multiplication by 4.
y=-x-9
Divide -36-4x by 4.
