1. TI-89 help

ok i have like 5 equations that i want to solve simultaneously, that includes 5 variables. i want to know how i can do this on my ti-89.

all of the equations are set to some value. i want to be able to enter the equations into my calculator and then get the values for the variables.

2. Hello,

Enter
Code:
solve(side1a=side2a and side1b=side2b and ... and side1e=side2e,{variable1,variable2,...,variable5})
You have to seperate the equations with " and " (including the spaces)

are there two versions of the ti-89, one that is programmable and one that is not programmable?

4. What do you mean ? You just put it where you enter "6*4" for example
