$2z+z^2x=x$

$2y+y^2z=z$

$2x+x^2y=y$

I know, this isn't a very hard problem, thus, we should compete in terms of how many minutes (or hours) that we used to come up with a good solution. I said good but not smart because to me:

$\text{all workable solutions, be them short or long}=\text{good solutions}$
