2x-4z=-1-y
Subtract y from both sides.
2x=-1-y+4z
Add 4z to both sides.
2x=-y+4z-1
The equation is in standard form.
\frac{2x}{2}=\frac{-y+4z-1}{2}
Divide both sides by 2.
x=\frac{-y+4z-1}{2}
Dividing by 2 undoes the multiplication by 2.
x=-\frac{y}{2}+2z-\frac{1}{2}
Divide -1-y+4z by 2.
y-4z=-1-2x
Subtract 2x from both sides.
y=-1-2x+4z
Add 4z to both sides.
