2x-12=-4y
Subtract 4y from both sides. Anything subtracted from zero gives its negation.
2x=-4y+12
Add 12 to both sides.
2x=12-4y
The equation is in standard form.
\frac{2x}{2}=\frac{12-4y}{2}
Divide both sides by 2.
x=\frac{12-4y}{2}
Dividing by 2 undoes the multiplication by 2.
x=6-2y
Divide -4y+12 by 2.
4y-12=-2x
Subtract 2x from both sides. Anything subtracted from zero gives its negation.
4y=-2x+12
Add 12 to both sides.
4y=12-2x
The equation is in standard form.
\frac{4y}{4}=\frac{12-2x}{4}
Divide both sides by 4.
y=\frac{12-2x}{4}
Dividing by 4 undoes the multiplication by 4.
y=-\frac{x}{2}+3
Divide -2x+12 by 4.
