The solution is -$\frac{8}{9}$

Work Step by Step

x+$\frac{1}{9}$=-$\frac{7}{9}$ Subtract $\frac{1}{9}$ from both sides x+$\frac{1}{9}$-$\frac{1}{9}$=-$\frac{7}{9}$-$\frac{1}{9}$ x= $\frac{-7-1}{9}$ x=-$\frac{8}{9}$ The solution is - $\frac{8}{9}$ Check Replace x with -$\frac{8}{9}$ x+$\frac{1}{9}$=-$\frac{7}{9}$ -$\frac{8}{9}$+$\frac{1}{9}$=-$\frac{7}{9}$ $\frac{-8+1}{9}$=-$\frac{7}{9}$ -$\frac{7}{9}$=-$\frac{7}{9}$
