## Prealgebra (7th Edition)

The solution is $\frac{9}{14}$
z-$\frac{5}{14}$=$\frac{4}{14}$ Add $\frac{5}{14}$ to both sides z- $\frac{5}{14}$+$\frac{5}{14}$=$\frac{4}{14}$+$\frac{5}{14}$ z= $\frac{4+5}{14}$ z=$\frac{9}{14}$ The solution is $\frac{9}{14}$ Check Replace z with $\frac{9}{14}$ z-$\frac{5}{14}$=$\frac{4}{14}$ Replace y with $\frac{9}{14}$ $\frac{9}{14}$-$\frac{5}{14}$ =$\frac{4}{14}$ $\frac{9-5}{14}$=$\frac{4}{14}$ $\frac{4}{14}$ =$\frac{4}{14}$
