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