Work Step by Step

We are given the expression $\frac{5a-7y}{2+m}$ and asked to evaluate the expression where $a=2$, $y=-2$, and $m=-26$. We can plug in these values in order to evaluate. $\frac{5(2)-7(-2)}{2+(-26)}=\frac{(5\times2)-(7\times-2)}{2-26}=\frac{10-(-14)}{2-26}=\frac{10+14}{2+(-26)}=\frac{24}{-24}=-1$
