Dear all,

This is the first time using Mathematica.
I'm trying to understand why when evaluating an expression of the form:

0.8*x1 + (-0.2+0.2)*x2;

where x is an variable for which I don't have a value, the programs delivers


How can I overcome this problem, since I need the program just to deliver


in order to continue with further calculations?

Thanks for your help
