Is this what you have? I doubt it can do matrices at all, given the single-line output. You will probably have to row-reduce by hand, but this particular problem should be fairly easy (it's only a 3x3, after all).
I have a Ti30x and my instructor is telling me that I need to perform this problem using the rref function, which the Ti30x doesnt have. I have to show a ck for my solution also. Can anybody help?
10x+6y+z=7
5x-9y-2z=3
15x-12y+2z=-5
Thank you In advance!!

Hi Firefightinfool,
I don't know about the TI30x, but on a TI-84+, you simply enter the matrix into your calculator, say Matrix A. I assume you can do that. You'll use the coefficients and the constant like
Then find your rref( ) (Reduced Row Echelon Form).
On a TI-84 its under matrix math.
Just enter rref([A]) and read the last column for your solutions.
You should get
If THIS is what the face of your calculator looks like, I don't see a way to enter a matrix array. Just not familiar with this model.
