Strange behavior solver app - V.20160829

[tecnovelez]

Good afternoon every one.

This afternoon my Hp prime updated correctly from the conkit.

The first thing I did, was check it had solved the problem with solve application.

Here the problem with the last firmware

http://www.hpmuseum.org/forum/thread-6487.html

I tried again with the example from the user manual,

EQ1: X-Y=-1
EQ2: (X^2)+(Y^2)=16

Now my solve aplication works, but the answer is not correct:

X=2
Y=28 388 218 142

In virtual calculator, now it doesn´t works.

In android, it works fine.

Please, can anyone check with the same equationes on your hp prime/virtual prime/android prime.

Thanks a lot.
