5x-y=18-8z
Subtract 8z from both sides.
5x=18-8z+y
Add y to both sides.
5x=y-8z+18
The equation is in standard form.
\frac{5x}{5}=\frac{y-8z+18}{5}
Divide both sides by 5.
x=\frac{y-8z+18}{5}
Dividing by 5 undoes the multiplication by 5.
8z-y=18-5x
Subtract 5x from both sides.
-y=18-5x-8z
Subtract 8z from both sides.
-y=18-8z-5x
The equation is in standard form.
\frac{-y}{-1}=\frac{18-8z-5x}{-1}
Divide both sides by -1.
y=\frac{18-8z-5x}{-1}
Dividing by -1 undoes the multiplication by -1.
y=5x+8z-18
Divide 18-5x-8z by -1.
