-3x+12=-6y
Swap sides so that all variable terms are on the left hand side.
-3x=-6y-12
Subtract 12 from both sides.
\frac{-3x}{-3}=\frac{-6y-12}{-3}
Divide both sides by -3.
x=\frac{-6y-12}{-3}
Dividing by -3 undoes the multiplication by -3.
x=2y+4
Divide -6y-12 by -3.
-6y=12-3x
The equation is in standard form.
\frac{-6y}{-6}=\frac{12-3x}{-6}
Divide both sides by -6.
y=\frac{12-3x}{-6}
Dividing by -6 undoes the multiplication by -6.
y=\frac{x}{2}-2
Divide -3x+12 by -6.
