3s_{1}=2-5s_{2}
Subtract 5s_{2} from both sides.
\frac{3s_{1}}{3}=\frac{2-5s_{2}}{3}
Divide both sides by 3.
s_{1}=\frac{2-5s_{2}}{3}
Dividing by 3 undoes the multiplication by 3.
5s_{2}=2-3s_{1}
Subtract 3s_{1} from both sides.
\frac{5s_{2}}{5}=\frac{2-3s_{1}}{5}
Divide both sides by 5.
s_{2}=\frac{2-3s_{1}}{5}
Dividing by 5 undoes the multiplication by 5.
