Cannot solve a system of equations using solve()

Hi,

 

I tried following the instructions on

https://h30434.www3.hp.com/t5/Calculators/Solving-a-system-of-linear-equations-using-a-parameter/td-...

but I can't get it to work on my calculator.

 

Here is a link with screenshots of my attempt and the software/hardware version of the calculator.

Thank you for looking it over.

Are you using the wrong brackets? I tried your screen shot with the double brackets [[ ]] and got the equation returned. When I tried just [ ] (shift-5) I got the values {[4.999... 13.49... 10.01...]}

Hi!, @Eff_five :

Can you please, write complete the system indicates in your example ?.

If you see, the example write for Cyrille de Brebisson, in the first example of other post, it's correct but configure to CAS Mode, in Function Apps.

For see, the total system, press Show.

In the comparison with Wolfram Alpha, in Approximate mode, the result, is same ...
