Assuming a, b, c and d are known, what is the best method to resolve the remaining variables: x, y, such that the resulting number is a specific integer.
I second xilman's question, where did this function come from?

I'll call it F(a,b,c,d,x,y)

Knowing what kind of critter this is, would be of considerable help in addressing the question of solving

F(a,b,c,d,x,y) = N
