Solving Multivariable Linear Systems:

3x-5y+5z = 1

5x-2y+3z = 0

7x-y+z = 5

I am confused on how to solve this. I'm supposed to use the Row-Echelon 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
