The solution is -$\frac{2}{3}$

x+$\frac{1}{3}$=-$\frac{1}{3}$ Subtract $\frac{1}{3}$ from both sides x+$\frac{1}{3}$-$\frac{1}{3}$=-$\frac{1}{3}$-$\frac{1}{3}$ x= -$\frac{2}{3}$ The solution is - $\frac{2}{3}$ Check Replace x with -$\frac{2}{3}$ x+$\frac{1}{3}$=-$\frac{1}{3}$ -$\frac{2}{3}$+$\frac{1}{3}$=-$\frac{1}{3}$ $\frac{-2+1}{3}$=-$\frac{1}{3}$ -$\frac{1}{3}$=-$\frac{1}{3}$
