I really like that you're patient enough to write everything out on the board. It must get tiring, but it really helps me understand!

Thank you so much for making these lecture courses available. I wish I had you as a professor a long time ago, but I think we are close to the same age, so you might have been a student too. ((50yrs old)). You are a wonderful teacher of mathematics.

At minute 12:10 / 1:14:19 why was -x5 not included in the equation of like terms when solving for W? orginally it was stated that only X6 and X7 were considered artificial variables defining w. I kept watching and see that you corrected it.

What about the ZERO on the RHS in place of b2??? Isn't it Degenerate?

What if a slack variable is in the basis set? Is the system still redundant or we need only artificial variables to comment about redundancy?
