Insert 1.4 for x1^2+x3^2 in the first equation and you'll see that the two surfaces do not intersect ...
I don't know whether MATLAB offers the possibility to deduce simpler equations for lower dimensional manifolds in IR^n that are given by a system of nonlinear equations. You may try MATLAB's "solve" command.
Best wishes
