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