Hello everyone, every row operation I make now is taking out the 0's i just made, any ideas on what I can do from here?
Here is my work:

Also I was confused on how this works, my professor did an example:
3x+2y+z = 8;
x = a
y = b
z = 8 - 3a - 2b
I get this part but then he does the following:

Where is he getting those values? The first one looks like he let a = 0 and b = 0, then ur left with just 8, but I'm not sure.
Thanks.
