2x+2z=14-2y
Subtract 2y from both sides.
2x=14-2y-2z
Subtract 2z from both sides.
2x=14-2z-2y
The equation is in standard form.
\frac{2x}{2}=\frac{14-2z-2y}{2}
Divide both sides by 2.
x=\frac{14-2z-2y}{2}
Dividing by 2 undoes the multiplication by 2.
x=7-z-y
Divide 14-2y-2z by 2.
2y+2z=14-2x
Subtract 2x from both sides.
2y=14-2x-2z
Subtract 2z from both sides.
2y=14-2z-2x
The equation is in standard form.
\frac{2y}{2}=\frac{14-2z-2x}{2}
Divide both sides by 2.
y=\frac{14-2z-2x}{2}
Dividing by 2 undoes the multiplication by 2.
y=7-z-x
Divide 14-2x-2z by 2.
