Step-by-step explanation:

In order to solve this problem we will assume some values of x which will give us integer values of y.

Substituting x=8 in our equation we will get,

Substituting x=24 in our equation we get,

Substituting x = 40 in the equation we get,

Therefore, our three combinations will be (8,42), (24,36) and (40,30).
