Simplex Method & Pivoting on a Ti-nspire cx

Hi, I was wondering if someone could help me with a question about the Ti-inspire cx? I’m currently taking Business & Finite math mathematics and we are in the last 4th section of the semester; over linear programming. Currently we are going over the Matrix simplex method & pivoting and I cannot figure out how to find/used or even download a Smplx programming on my Ti-nspire cx that I am using. I do not have a Ti-84/83 at my disposal. Can someone help me?

I learned the simplex method a long time ago and have since forgotten. How do you do it? (Note: Yes, I know Google exists, I have a different motivation.)

Also, does this help?

Simplex Method
1)Set the unknowns as the variables.
2)Determine the objective function.
3)Write the constraints.
4)Convert to a system of equations with slack variables.
5)Write the Initial Simplex Tableau
6)Find the pivot column-Most negative entry in the last row-If there is a tie, use the column furthest to the left
7)Find the pivot row-Smallest nonnegative ratio of constants to pivot column entries.-If there is no nonnegative ratio, then there is no maximum.-If there is a tie, use the row closest to the top.
8)Pivot
9)Repeat until all entries in last row are nonnegative.-If there is a 0 in the bottom row of a non-basic variable, then another solution can be found using this column as another pivot column.
10)Read the solution

Does this help?

By any chance did you try the program that I linked to?
