_____________________
Step-by-step explanation:
There are two different kind of ways in order to complete this real world scenario, but, we'll start with the most easiest and basic.
Both [tex]\boxed{y \ and \ x}[/tex] equal 176, as the problem stated out. Then we simply plug it in with the information that was brought out.
