Hi, I've just been given a set of revision questions for matrices and I'm having problems with the following question: http://tinypic.com/ejbssz.jpg" My task is to find the general solution of this system (if there is any). Do I start off by reducing it to row echelon form and then reduced row echelon? My first step would be to divide the first line by 3 to get a 1 on the far left...but that would mean I would have fractions as well which makes everything so 'messy.' Is that the correct first step to this question? Help and advice appreciated! Thank you!
