Can someone out there please give me a crash course on matrices and multiplicative inverses and all that jazz.......and if you know how to do this stuff on a TI-83 Plus, that would be a good help too...

Thank you soooooooo much! :D
 
I'm sorry, but we really can't teach classes here. The reason matrices "all all that jazz" took a chapter or two in your text (and an entire chapter in your calculator's owners manual) was that the various topics, concepts, and techniques can't be covered in a simple posting.

Please post the full and exact text of the exercise with which you are having difficulty, the complete instructions, a detailed description of any required graphic, and a listing of the steps and reasoning you have tried thus far.

Thank you.

That may be; I can't say, though, if true, I know how you feel: I had to teach the algebra at my high school, because none of the "teachers" understood it.

If you have to learn these topics on your own, there are plenty of online resources. You might want to start with Google, and search on important terms. For instance, a quick search using the keywords "matrix multiplication" (without the quote-marks) turns up a couple of million results; you should be able to find helpful a lesson or two in the first page of hits.

Good luck!
