Find: [0 1 6 -2/1 0 -5 2/3 3 -1 4/-4 -1 (16) -3] NOTE: That is a 4x4 matrix above (sorry I can't type it out properly here) with the /'s separating each row. by carrying a Gauss-Jordan reduction just far enough to make the corresponding matrix triangular. (Remember to allow for the effects of the elementary operations on the determinant).
I'm not sure how to go about this. Help would be greatly appreciated!
