18x-5z=8-2y
Subtract 2y from both sides.
18x=8-2y+5z
Add 5z to both sides.
18x=8+5z-2y
The equation is in standard form.
\frac{18x}{18}=\frac{8+5z-2y}{18}
Divide both sides by 18.
x=\frac{8+5z-2y}{18}
Dividing by 18 undoes the multiplication by 18.
x=\frac{5z}{18}-\frac{y}{9}+\frac{4}{9}
Divide 8-2y+5z by 18.
2y-5z=8-18x
Subtract 18x from both sides.
2y=8-18x+5z
Add 5z to both sides.
2y=8+5z-18x
The equation is in standard form.
\frac{2y}{2}=\frac{8+5z-18x}{2}
Divide both sides by 2.
y=\frac{8+5z-18x}{2}
Dividing by 2 undoes the multiplication by 2.
y=\frac{5z}{2}-9x+4
Divide 8-18x+5z by 2.
