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