It's actually simple - the documentation tells you exactly how to do it
using the cancel package as an example :-) - see the section "TeX and
LaTeX extensions" in

   https://docs.mathjax.org/en/v2.5-latest/tex.html

All you need to do to incorporate that into org is to make it add the
script when you export. That is done by appending it to
org-html-mathjax-template:

--8<---------------cut here---------------start------------->8---
(setq org-html-mathjax-template (concat org-html-mathjax-template "
<script type=\"text/x-mathjax-config\">
MathJax.Hub.Register.StartupHook(\"TeX Jax Ready\",function () {
  MathJax.Hub.Insert(MathJax.InputJax.TeX.Definitions.macros,{
    cancel: [\"Extension\",\"cancel\"],
    bcancel: [\"Extension\",\"cancel\"],
    xcancel: [\"Extension\",\"cancel\"],
    cancelto: [\"Extension\",\"cancel\"]
  });
});
</script>
"))
--8<---------------cut here---------------end--------------->8---
