$\displaystyle \frac{|x-y|}{|y-x|}

$

x cannot equal y.

I'm stumped on this, I'm being told the answer is 1 but I don't understand how.

If someone could explain this indepth I'd be so grateful! Thank you.

Ohh, I think I get it now. Thank you! I'm very bad with absolute value...

Edit: Wait, I'm still confused. Where does $\displaystyle \frac{|x-y|}{|-x-y|}$ Come from?
