2x-z=25-y
Subtract y from both sides.
2x=25-y+z
Add z to both sides.
2x=25+z-y
The equation is in standard form.
\frac{2x}{2}=\frac{25+z-y}{2}
Divide both sides by 2.
x=\frac{25+z-y}{2}
Dividing by 2 undoes the multiplication by 2.
y-z=25-2x
Subtract 2x from both sides.
y=25-2x+z
Add z to both sides.
