The program is the following:

It's suposed to solve the system of equations "eqns" where the variables are in "unknown" and are T1,T2,T3...T9. Then this is done for 100 diferent time marks (0-->1second). As you can see, the solver's output is the "eqns" matrix and the error msg "s not a quantified system of equations and inequalities.". The solve uses the matrix form of both "unknown" and "eqns" labeled as "unknown2" and "eqns2" but it was just a guess to make it work, this shouldn't be necesary.

All help is apreciated. thanks!

Edit: the last part with the "Do" instruction is not part of the program, just there for other purposes
