I'm also super new to Maxima, but can it factor out constants from an expression? Or could you create a fraction between the left and right side, reduce it and then see if it is the simplified version? Of course being carfeul not to divide by zero.

It's still not perfect. What if they enter 2y=16? The current algorithm only deals with stuff like y+2=10.
I am very busy at the moment, but at some point in time, I want to look at doing this in a general way. I filed a bug against myself, http://bugs.lon-capa.org/show_bug.cgi?id=6550 - trivial this is not, unless I am missing something.
