Hi everyone

I want to solve an easy exercise with 2 unknown and 2 equations.

x+y=5

x*y=5

I try to solve it with the function in the 2D menu (it looks like beneath).

{ x+y=5 I

{ x*y=5 I x,y

It normally works, but now the calculator (Casio Classpad 300Plus) gives me the solution:

{x+y=5,x*y=5}.

So it does not solve the equations.

I own this calculator since more than 6 years and I never had this problem before.

Does somebody has some ideas how to solve the problem?

thank you
