2x+5z=18+y
Add y to both sides.
2x=18+y-5z
Subtract 5z from both sides.
2x=y-5z+18
The equation is in standard form.
\frac{2x}{2}=\frac{y-5z+18}{2}
Divide both sides by 2.
x=\frac{y-5z+18}{2}
Dividing by 2 undoes the multiplication by 2.
x=\frac{y}{2}-\frac{5z}{2}+9
Divide 18+y-5z by 2.
-y+5z=18-2x
Subtract 2x from both sides.
-y=18-2x-5z
Subtract 5z from both sides.
-y=18-5z-2x
The equation is in standard form.
\frac{-y}{-1}=\frac{18-5z-2x}{-1}
Divide both sides by -1.
y=\frac{18-5z-2x}{-1}
Dividing by -1 undoes the multiplication by -1.
y=2x+5z-18
Divide 18-2x-5z by -1.
