y= -$\frac{1}{8}$

Work Step by Step

Add $\frac{1}{8}$ to both sides of the equation to isolate the variable. -$\frac{1}{8}$+y=-$\frac{1}{4}$ y=-$\frac{1}{4}$+$\frac{1}{8}$ y=-$\frac{2}{8}$+$\frac{1}{8}$ y=-$\frac{1}{8}$ Check the answer. -$\frac{1}{8}$+(-$\frac{1}{8}$)=-$\frac{1}{4}$ -$\frac{2}{8}$=-$\frac{1}{4}$ -$\frac{1}{4}$=-$\frac{1}{4}$
