Reducing a matrix to echelon form

[QUOTE="Mohamed Abdul, post: 5879962"] [h2]Homework Statement [/h2] [ATTACH=full]214844[/ATTACH] (i) Reduce the system to echelon form C|d (ii) For k = -12, what are the ranks of C and C|d? Find the solution in vector form if the system is consistent. (iii) Repeat part (b) above for k = −18 [h2]Homework Equations[/h2] Gaussian elimination I used here: [URL]http://mathworld.wolfram.com/GaussianElimination.html[/URL] [h2]The Attempt at a Solution[/h2] [ATTACH=full]214845[/ATTACH] [ATTACH=full]214846[/ATTACH] [/B] I've attempted reducing the matrix but have run into this problem where I have two zeroes leading in the last three rows. I don't know what I am doing wrong, so any help would be greatly appreciated. I can't continue with either parts b or c without solving part a, and I'm not too sure about those parts either. [/QUOTE]
