391

we can take x=391 and y= 0

here x>y, and x+y=391

we can take x=391 and y= 0

here x>y, and x+y=391

=> x ( 1 + y ) = 391

since x and y are integers , therefore we can solve it simply factorising 391 .

391 = 17 * 23 = x ( 1 + y )

since x > y

=> x = 23

1+y = 17 => y = 16

so x + y = 23 + 16 = 39
