# Proofs: Problem 3

### Hints

You need to find specific concrete values for x, y, and z that make the equation false.

Go for small integer values, so the reader can easily verify that you're right.

Don't try to write a general argument or a general discussion of which values do/don't
satisfy the equation. It's fine to explore this on your own, if you are interested.
But don't put that into your answer. A simple concrete example is more deadly than
a complex discussion.
