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