Answer by josgarithmetic(39617) (Show Source): You can put this solution on YOUR website!
The equation can represent a line, and the equation has infinitely many solutions, so x+y is not any specific number. BUT you want INTEGERS x and y.

-
What happens if y is solved in terms of x and x is solved in terms of y?

-
What is sum, x+y?
..........

Maybe making a graph, identifying some integer (x,y) points, and finding x+y for each of those would be easier, but would it give you better information?
