I have a TI-89 titanium calculator. I am trying to use the solve() function under the algebra menu to solve multiple equations. What is the format for entering the equations and the variables?

Type it like this: solve( equation1 and equation2 and moreEquations, {list of variables to solve for})

Put all of your equations right after the opening parenthesis separated by the word *and*, then a comma, then within curly braces each variable you want to solve for each separated by a comma.

That's because there's an infinite number of solutions to your equation. Replacing the @n with any integer gives you a new, different solution.

This calculator cannot solve equations and does not have an x key. You will require a calculator with a computer algebra system like the TI-89 or TI-nSpire CAS.

Yes you can. Use the Solve( function. You will find it under Math

There are a few routines to solve simultaneous LINEAR equations that are embedded in the Operating system of the calculator.

If you need download and install instructions, you will find them here.

With the ALPHA keyboard, Type in the NewProb command and press ]ENTER] It resets the one-letter variables to their default status.

Alternatively, you can use the CATALOG of commands to launch the NewProb command.

Another way is

In HOME directory, press the [2nd][F1] to activate the F6 key. In the menu list, press 1:Clear a-z and ]ENTER].

If you have to use the variable x multiplied by a function (sin, cos, tan, log, etc) do not used implied multiplication: enter the [*] explicitly.

Sorry, but you cannot calculate limits of functions with this calculator. It does not have a Computer `Algebra System (CAS). For that you need a graphing calculator with CAS: Casio ClassPad 300, 300PLUS, 330, HP 48 GII, HP49 G/ G+, HP 50G, TI-NSPIRE CAS, TI89 Titanium, TI 92/92PLUS, TI Voyage 200 PLT. It is still a very good scientific (non graphing) calculator

However, you can calculate numerical derivatives, and numerical integrals, solve linear and non-linear equations.

Even though this post does meet your expectations, do not let that prevent you from rating it.

use the simultaneous equation solver software available on ur ti-89 and enter the equation in the form of augmented matrix and you will get ur answer.

The TI-30XA cannot solve algebraic equations. You need a more advanced calculator for that, like the TI-89.
