actually an easier way is to plug the matrix in at the beginning as a 4 x 5. (Pretend the dashed line is gone.)

Hit rref:. Plug in A. it gives the same answer in a gazillion less steps

@McFacecriminal: Just a warning...you don't always get the correct answer when you do it that way. Sometimes it works, sometimes it doesn't. I'm sure there's a reason for it, but I just haven't sat down and tried to figure out why this is the case. (When it works, though, you're right - it's much quicker and easier.)

I love you so freaking much. This helped me finish my math for summer school completely. This was the last thing I needed because I couldn't figure it out doing it by hand. THANK YOU! You ish god!*bows*

The explanation is clear and well presented. It helped me a lot studying for my finite math final. Volume though needs adjustment it is too low. Otherwise great video, Thanks!

Just wanted to let you know, even with my computer's volume and youtube's volume set at its highest level, you cannot be heard.
