I need to find 5 or more ordered pairs (x,y)
In which xy = x + y
like (0,0) and (2,2)
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:
xy= x+y ---->
xy - x = y --->
x(y-1) = y ---->
x = y/(y-1)
Take e.g. y = 9/10 ---> x = -9
