$m=2$

#### Work Step by Step

We need a common denominator (bottom of the fraction) to add the numerators (tops of the fractions). Thus, we multiply $\frac{2m}{7}$ by $\frac{2}{2}$ to get $\frac{4m}{14}$. (This is legal because $\frac{2}{2}$ is equal to one). We then add to find that $\frac{7m}{14}$$=1$. We simplify the fraction to get that $m/2=1$. In order to cancel out division, we use multiplication, so we multiply both sides by 2 to get that $m=2$.
