The case Gutin describes conforms to the documentation, viz. `$x\beta$-` should produce math mode LaTeX as I read the next paragraph.
From (info "(org) LaTeX fragments"):
• Text within the usual LaTeX math delimiters. To avoid conflicts
with currency specifications, single ‘$’ characters are only
recognized as math delimiters if the enclosed text contains at most
two line breaks, is directly attached to the ‘$’ characters with no
whitespace in between, and if the closing ‘$’ is followed by
whitespace, punctuation or a dash.
But the $...$ and $$...$$ seem fragile. I recall advice to avoid them in favor of \(...\) and \[...\].
FWIW, my sanity has been aided by using yf/org-electric-dollar[1], which inserts `\(\)` when I type `$` and leaves point where you need it to enter math mode LaTex. A dash after the closing parenthesis is no problem.
HTH,
Chuck
