Question 1077191: Find all integers x for which there exists an integer y such that
1/x + 1/y = 1/7
(In other words, find all ordered pairs of integers (x,y) that satisfy this equation, then enter just the x's from these pairs.)
You can put this solution on YOUR website! I get 8, 14, and 56

I rearranged to and then looking at the right hand side:
x-7 must divide 7x evenly, which happens for x=8, 14, and 56.
