HP50g , how can i Solving multiple equations in ALG mode (not in RPN mοde).

[Nick15]

Hello

For my HP50g , how can i Solving multiple equations in ALG mode ?(not in RPN mοde).

There is a example in the manual on capter 7 , but only in RPN mode.

How can i convert it in ALG mode? (Only with the Solve function)

Example3  from page 241:

The following screen shot shows the solution of the system X^2+XY=10, X^2-Y^2=-5,
How can write and solve the above example in ALG mode , solution ONLΥ withe the"Solve" function

How can I just write it?

Hi!, @Nick15:

You can SOLVE, the system, of equation's ... First, see the link ... http://isa.umh.es/temas/calc/ss49docs/solve49.htm

For non-linear equation, you can used other very good library, from ... http://www.hpcalc.org/details.php?id=7124

'X^2+X*Y=10'

'X^2-Y^2=-5'

Results:

X: -2

Y: -3

X: 2

X: 3

In comparison, with Wolfram Alpha ...
