For this weekend I hope to improve Math-o-mir’s symbolic calculator to be able to solve simple systems of equations. Currently the Math-o-mir’s symbolic calculator only know how to work with a single equation.

The idea is that user selects two or more equations, and at right-mouse-click the Math-o-mir produces one single equation (result) by combining them all – substitution method will be used.

I am not sure what to do if user selects some unrelated equations (un-needed, redundant…) together with relevant ones. I suppose that Math-o-mir should produce no result if it cannot reduce the system to one single equation.
