Answer
23
Work Step by Step
We are given the expression $\frac{5a-7y}{2+m}$ and asked to evaluate the expression where $a=1$, $y=4$ and $m=-3$. We can plug in these values in order to evaluate.
$\frac{5(1)-7(4)}{2+(-3)}=\frac{(5\times1)-(7\times4)}{2-3}=\frac{5-28}{2-3}=\frac{5+(-28)}{2+(-3)}=\frac{-23}{-1}=23$
