"7 times y" $\rightarrow$ 7y, "2 more than 7 times y" $\rightarrow$ 2+ 7y, "x is 2 more than 7 times y" $\rightarrow$ x=2+ 7y, If y=5, we calculate x from the last equation, $x=2+7(5)=2+35=37.$ To evaluate the expression, replace x with 37 and y with 5: $\displaystyle \frac{x-y}{4}=\frac{37-5}{4}=\frac{32}{4}=8$
