emacs lisp: How to remove/delete an element of a list?
===

I tried my first steps with emacs lisp to remove the element `"\\.synctex\\.gz"` from `LaTeX-clean-intermediate-suffixes`:


    (eval-after-load 'latex
      '(setq my-LaTeX-clean-intermediate-suffixes (remove '"\\.synctex\\.gz" LaTeX-clean-  intermediate-suffixes)); that's not working
      '(setq LaTeX-clean-intermediate-suffixes
    	 (append my-LaTeX-clean-intermediate-suffixes (list "-blx\\.bib" "\\.run\\.xml"))))

How can I remove this element here? I found `remove` and `delete`, tried them both, but I get an `wrong-number-of-arguments`-type of error.
