Math 1324: Sec. 6.1 & 6.2 Intro to solving systems of eqns (by hand and by rref)

Herein are directions to using the TI calculators to solve systems of equations easily.
I also show how to solve a system of equations "by hand," using the 3 legal moves allowed,
the 3 elementary row operations. You're going to need to know how to use those in Sec. 7.4,
because the Simplex Method involves elementary row operations almost exclusively. And there is NOT a program on your calculators for the Simplex Method. Just ignore the "Math 2318" written on the board; this material is useful for both Math 2318 and Math 1324.
