Hello.
Dear forum users!
I would like to solve a system of linear equations in Smath Solver as in Mathcad. Is it possible?

Yes, you can. But beware, there are several solvers.
For single equations, solve() is usually enough.

For systems, I try these functions as in order until a result comes;
  • roots()
  • Findroot()
  • al_nleqsolve()
  • maple solve (or maxima)

Regards

It is obtained by symbolic evaluation.
Since result is only variables.

If you perform a numeric calculation and wish outcome as a number,
then you will need numerical evaluation.

These two can be changed via 'Right click>Optimization'.
