Re: Ti92 solver

For the TI-92, the following works to solve many systems of equations. You
enter the expressions on the left and the calculator returns those on the
right:

Solve(x+y=5,y)                         y=5-x
Solve(x^2+y^2=13,x)|ans(1)             x=3 or x=2
y=5-x|x=3                              y=2
y=5-x|x=2                              y=3

You should auto-paste as much as possible rather than re-typing (particularly
that y=5-x).  If you're not familiar with the "with operator", |, check your
manual.  It is entered as 2nd K.

For the TI-89 or 92 Plus, just enter:

Solve(x+y=5 and x^2+y^2=13,{x,y})

Note: those are braces, not parentheses used in {x,y}.

Hope this helps.
