1. The problem statement, all variables and given/known data Find the general solution 2. Relevant equations Row operations Gaussian elimination 3. The attempt at a solution This is has happened twice now and I'm not too sure how to deal with it. The last row ends up being all zeros except in that spot. I need to make this into an echelon matrix and for that I need a 1 in the 3rd entry of row 3. Not sure how to get it like that.
