I need to find 5 or more ordered pairs (x,y)
In which xy = x + y
like (0,0) and (2,2)
0,0
2,2
1/2,1
1,1/2
i need one more
How about two different x's and y''s?
(2,3) = 1,5)
this is the problem: xy= x+y
or the product of xy equals the sum of x and y.
example: x= .5 and y= 1
where x times y equals 0.5 and x plus y also equals 0.5.
i need one more example so far I have:
(0,0)
(2,2)
(1/2,1)
(1,1/2)
xy= x+y >
xy  x = y >
x(y1) = y >
x = y/(y1)
Take e.g. y = 9/10 > x = 9
