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