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