12x=9+9y
Add 9y to both sides.
12x=9y+9
The equation is in standard form.
\frac{12x}{12}=\frac{9y+9}{12}
Divide both sides by 12.
x=\frac{9y+9}{12}
Dividing by 12 undoes the multiplication by 12.
x=\frac{3y+3}{4}
Divide 9+9y by 12.
-9y=9-12x
Subtract 12x from both sides.
\frac{-9y}{-9}=\frac{9-12x}{-9}
Divide both sides by -9.
y=\frac{9-12x}{-9}
Dividing by -9 undoes the multiplication by -9.
y=\frac{4x}{3}-1
Divide 9-12x by -9.
