This works:

--8<---------------cut here---------------start------------->8---
#+LaTeX_CLASS: article

* test
  This is just a test [fn:test].

[fn:test] This is an equation: \(x = y\).
--8<---------------cut here---------------end--------------->8---

It is generally a good idea (and not just in org-mode) to avoid $...$
and $$...$$ for math. The recommended way is \(...\) for inline equations
and \[...\] for diplayed math.
