Answer

$m=\frac{83}{20}$

Work Step by Step

We are given the equation $m-\frac{7}{5}=\frac{11}{4}$. Add $\frac{7}{5}$ to both sides. $m-\frac{7}{5}+\frac{7}{5}=\frac{11}{4}+\frac{7}{5}$ $m+0=\frac{11}{4}+\frac{7}{5}=\frac{11\times5}{4\times5}+\frac{7\times4}{5\times4}=\frac{55}{20}+\frac{28}{20}=\frac{55+28}{20}=\frac{83}{20}$ $m+0=\frac{83}{20}$ Therefore, $m=\frac{83}{20}$.
