A strange question

  1. Feb 8, 2006 #1
    One of my friends asked me this, and I have no idea how to get the answer. I don't even know if there is an answer... if someone could help, that'd be great:

    xy = x/y = x-y

    If y cannot equal 0, what is the value of x and y?

    Thanks :D

    Unless I goofed in the calculation, x is -1/2 and y is -1. Work out xy = x/y to see that y is either +1 or -1, then work out the subtraction.
