-\frac{9}{5}+3a=x
Swap sides so that all variable terms are on the left hand side.
3a=x+\frac{9}{5}
Add \frac{9}{5} to both sides.
\frac{3a}{3}=\frac{x+\frac{9}{5}}{3}
Divide both sides by 3.
a=\frac{x+\frac{9}{5}}{3}
Dividing by 3 undoes the multiplication by 3.
a=\frac{x}{3}+\frac{3}{5}
Divide x+\frac{9}{5} by 3.
