1. The problem statement, all variables and given/known data find the general solution of the given system of equations: http://puu.sh/ncKaS/57a333f5b9.png [Broken] 2. Relevant equations Row Echelon Operations 3. The attempt at a solution http://puu.sh/ncKcm/3e2b2bd5ab.jpg [Broken] The correct answer given is x = 1, y = 1, z = 2, w = −3 I have done quite a few of these now around 5-6 and have gotten 3 correct. I don't know what my mistake with this one is. We are using Gaussian elimination.
