Work Step by Step
"$5$ times $y$" $\rightarrow 5y$,
"$2$ more than $5$ times $y$" $\rightarrow 2+5y$,
"$x$ is $2$ more than $5$ times $y$" $\rightarrow x=2+5y$
If $y=4$, we calculate x from the last equation,
$x=2+5(4)=2+20=22.$
To evaluate the expression, replace x with $22$ and y with $4$:
$\displaystyle \frac{x-y}{3}=\frac{22-4}{3}=\frac{18}{3}=6$
