12x=8+4y
Add 4y to both sides.
12x=4y+8
The equation is in standard form.
\frac{12x}{12}=\frac{4y+8}{12}
Divide both sides by 12.
x=\frac{4y+8}{12}
Dividing by 12 undoes the multiplication by 12.
x=\frac{y+2}{3}
Divide 8+4y by 12.
-4y=8-12x
Subtract 12x from both sides.
\frac{-4y}{-4}=\frac{8-12x}{-4}
Divide both sides by -4.
y=\frac{8-12x}{-4}
Dividing by -4 undoes the multiplication by -4.
y=3x-2
Divide 8-12x by -4.
