-9x=20+4y
Add 4y to both sides.
-9x=4y+20
The equation is in standard form.
\frac{-9x}{-9}=\frac{4y+20}{-9}
Divide both sides by -9.
x=\frac{4y+20}{-9}
Dividing by -9 undoes the multiplication by -9.
x=\frac{-4y-20}{9}
Divide 20+4y by -9.
-4y=20+9x
Add 9x to both sides.
-4y=9x+20
The equation is in standard form.
\frac{-4y}{-4}=\frac{9x+20}{-4}
Divide both sides by -4.
y=\frac{9x+20}{-4}
Dividing by -4 undoes the multiplication by -4.
y=-\frac{9x}{4}-5
Divide 20+9x by -4.
