Solve App problem
Hi
I bought HP Prime app for android and tried to solve some simple equation via built in Solve app but "Cannot find solution" error appeared.
Here are the steps I tried:

and the result is always

On my old HP49g I often used "solvesys 49 (solvesys.lib)" program(simultaneous nonlinear equation solver) for similar more complicated equations and was very satisfied. Is there a possibility to make it work with HP Prime?
Sorry for mistakes but English is not my native language.
Thanks in andvance.

Hi!:

You must select, as many variables, as there are, equations.
See, the images.

Kind Regards.

RE: Solve App problem
Thank you informach for quick replay but I just discover some weird results.
I checked "V" and "P" as variables and changed the values of "N" from 1 to 10.
If I put number 2,4 and 8 for "N" "Cannot find solution" error appears. Numbers 1,3,5,6,7,9,10 solve equation but variable "P" gives strange results (for example if I put for "N" 1000 "P" is 15 instead of 1562,5).
Thanks

Hi!:

See, in the User Guide, how you can, input equation's and variables, Chapter 14, pages 289/296.

RE: Solve App problem
I read all chapter 14 but don't now what I'm doing wrong.
Is there a way to install old program that I mentioned before "solvesys 49 (solvesys.lib)" originally written for HP49/50 to HP Prime?
Thanks

Hi!, kruki:

You can Solve App, only, one equation, each time.
See, from ... http://www.hp-prime.de/en/category/21-solutions-apps

Kind Regards.

No, there is not any way to install it.

Note however that the problem you are reporting in the android app you see should be resolved with the next android update.
