x=$\frac{1}{4}$
Subtract $\frac{7}{8}$ from both sides of the equation to isolate the variable. x+$\frac{7}{8}$=$\frac{9}{8}$ x=$\frac{9}{8}$-$\frac{7}{8}$ x=$\frac{2}{8}$ x=$\frac{1}{4}$ Check the answer. ($\frac{1}{4}$)+$\frac{7}{8}$=$\frac{9}{8}$ $\frac{2}{8}$+$\frac{7}{8}$=$\frac{9}{8}$ $\frac{9}{8}$=$\frac{9}{8}$
