Problem solving linear equation matrix system (symbolic calculation)

Dear all,

 

I would like to solve a linear equation system in Mathcad.

The question is how to solve it symbolically. I've already looked in the previous posts but unfortunately I haven't found the solution.

I really appreciate your support.

 

Best Regards.

 

Enrico

I guessed so and had already edited my reply above.

Looks like you want to solve for f3,f4,F1 and F2. A bit unusual but this gives us the results you expected if we replace the F in the results you give (should be F1, right?) by Q=F1.

Its not clear to me which system you want to be solved for which variables.

Your sheet does not show any equations.

Would one of the followings apply and be helpful?

BTW, are you aware the the numerics will interpret l as unit liter and J as unit Joule?

Dear Werner,

 

Thank-you for answering.

The linear equation system is {F} = [K] {f}.

Thank-you for your support.
