6x_{1}+16x_{2}=Z
Swap sides so that all variable terms are on the left hand side.
6x_{1}=Z-16x_{2}
Subtract 16x_{2} from both sides.
\frac{6x_{1}}{6}=\frac{Z-16x_{2}}{6}
Divide both sides by 6.
x_{1}=\frac{Z-16x_{2}}{6}
Dividing by 6 undoes the multiplication by 6.
x_{1}=\frac{Z}{6}-\frac{8x_{2}}{3}
Divide Z-16x_{2} by 6.
