Picking number here is the fastest way to deal with.
x is 8 because \(\frac{8}{7}\) the remainder is 1. Y is 9 because \(\frac{9}{7}\) gives 2 as remainder.
\(\frac{17}{7}\) the remainder is 3.
Hope this helps.

As all we know when the dividend less than divisor, it is equal to remainder. I chose x=1 and y=2, then x+y=3 which is still less than 7, therefore it is equal to remainder. I am not sure it is the correct way but it works.
