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