Please Help!!!!!!!!

In the following code at this link:

Simultaneous Solving Code

I have tried to run the program but I don't seem to getting anything from it and I have made sure 3-4 times that the code had been entered correctly, which it was.

I know I have to enter the coefficients before I run the program (XEQ S) but where do I enter them at? I tried XEQ I and XEQ J, but nothing. Can someone please walk me through this program; not the code, just using the program? I would greatly appreciate someone giving me an exact run through with a 3X3 example.

Thanks!!!

Alright, I have never used this program before, but what you need to do is store your coefficients in those variables. For example, for the A coefficient, you STOre A.

The answers will be on your stack, and you will have to rotate your stack to see them all (The R up arrow button, and R down arrow).

See if that makes some sense.

Also, if you are trying to learn the 33s, you might try reading some of the Learning Modules available at http://www.hp.com/calculators/scientific/33s/

These go through everything step by step (in RPN and Algebraic) and will help you better understand the calculator.

Thanks Ben!! The program in the hp 33s manual has it to where you press the XEQ A key and then you are prompted for each coefficient, but this program is different.

I now am able to use this program. I was trying to find the keys that would prompt me, but now I know I must enter the number then STO the number to the letter. Still more learning about this calc. to go.

Thanks again.
