The Calculator does not have a Computer Algebra System (CAS), and cannot perform algebraic operations with variables. However if you enter some expression with variables, it can solve for one unknown after it prompts you for the values of the others

This calculator cannot manipulate algebraic expressions. You can enter an expression and generate a table of values. You can enter an equation in one unknown and solve it. But you cannot do algebra.

You would need a calculator that has a Computer Algebra System (Algebra FX 2.0, or ClassPad 300/330). Sorry.

Yes it can be keyed in.

To enter the X, use the ALPHA followed by ). To enter the = sign, you use [ALPHA][CALC].

To use the calculator to SOLVE an equation you must enter the equation, then press [SHIFT][CALC] to (SOLVE). You will be prompted to solve for X. Follow it from there.

As to the case you show, the constant terms will drop and you are left with 26X=0, and the solution is X=0.

**Note: The calculator cannot do algebra with letter symbols. It does not have a Computer Algebra System or CAS.**

In answering your other question I did make a mistake: I looked at the wrong version of the manual. The Algebra FX 2 Plus does solve for eigenvalues. Under the CAS. Here is a screen capture to help you.

It is always risky to try to answer a question about a calculator of an undisclosed model.

To be able to symbolic algebra (with variables), one needs a calculator with CAS (or Computer Algebra System). These types of calculators are special graphing calculators. ( Not all graphing calculators have a CAS.)

To get back to your question: No, you cannot do algebra with a mere scientific calculator even a recent one. All you can do is define an equation with variables A,B,C,D, Y and X and press the Solve button if it exists. The calculator will ask: Solve for X?. If you say yes, you will be prompted for the values of all letters (A,B,C,D, Y) in your equation and the calculator will search for the value of X, that makes the left side of your equation equal to the right side.

It will display the X-value and the difference L-R.

The calculator does not have a CAS (Computer Algebra System). Therefore it cannot do symbolic algebra. It can only calculate numerical values.

You can enter algebraic expressions with symbols (X, variable), Y, A,B,C,D, and M but they will just be evaluated with the current values of A, B,C,D, Y, and M. If you use the SOLV program the unknown variable must be X.

Hello,

I suggest you reset the calculator by removing the main batteries. This will free up space to solve the problem.

Hope it helps.

The TI83 does not have a computer algebra system, so you cannot solve algebraic equations for a variable. For that you would need the TI89, TI92 or higher.
