Solving Multivariable Linear Systems:
3x5y+5z = 1
5x2y+3z = 0
7xy+z = 5
I am confused on how to solve this. I'm supposed to use the RowEchelon form.
Thanks.

argghhh! I don't like that method, however this page shows you step by step what to do

enter: 3 rows, 4 columns, then
3 5 5 1
5 2 3 0
7 1 1 5 
Wow, thanks.
