Since there is just one variable, you can try find_root instead of mnewton:

find_root (6*cos(2*x)-2*sin(2*x), x, 3, 4);
 => 3.76611553978892

To get more information you can try:

:lisp (load 
"/usr/share/maxima/5.13.0/share/linearalgebra/load-linearalgebra-lisp-files.lisp")

which should print a more specific error message.

Sorry for writing in English, I can't write in French. Hope this helps!
