If Maxima was able to do so I guess that Mathcad and even Prime should be able to solve that system as well.
You may use the symbolic solve command or in Mathcad 15 you may even set up a solve block and evaluate it symbolically (not possible to do so in Prime).
Something like
This was done in Mathcad 15 and as you can see, the solve block gives you the solution in a column vector, while the symbolic solve gives you a row vector.

No problem, all you did was OK.
Its the numeric processor throwing the red error as of undefined variables an it prevents the display of the result. Sometimes, if you move the region around, the result suddenly appears just to dispappear when you recalculate the sheet. You may call it a bug or an annoyance.
Anyway, the variable got its value correctly, you can prove it by evaluating the variable symbolically:
As I wrote in my first respones, the symbolic solve gives to the results presented in a row vector. Thats the reason Luc (and you) had to use two indices to address an element.
You may show all solutions in a column vector by using the transpose operator
and while you are at it, you could assign all variables at once using the vector you had used in solve:

That's it. Problem (if any) solved.
I had feared that mathcad 15 would complain about the size of the result and would not display it. But apparently that's not the case here.
You can also do the solution in one go:
etc.
And the problem can be structured as:
