-4x=18+9y
Add 9y to both sides.
-4x=9y+18
The equation is in standard form.
\frac{-4x}{-4}=\frac{9y+18}{-4}
Divide both sides by -4.
x=\frac{9y+18}{-4}
Dividing by -4 undoes the multiplication by -4.
x=-\frac{9y}{4}-\frac{9}{2}
Divide 18+9y by -4.
-9y=18+4x
Add 4x to both sides.
-9y=4x+18
The equation is in standard form.
\frac{-9y}{-9}=\frac{4x+18}{-9}
Divide both sides by -9.
y=\frac{4x+18}{-9}
Dividing by -9 undoes the multiplication by -9.
y=-\frac{4x}{9}-2
Divide 18+4x by -9.
