Explanation An elementary matrix is any matrix that can be obtained by performing an elementary row operation on an identity matrix. Given, A = [ 1 2 − 1 1 1 1 1 − 1 0 ] , C = [ 1 2 − 1 1 1 1 2 1 − 1 ] Here identity matrix I 3 will be I 3 = [ 1 0 0 0 1 0 0 0 1 ] In order to determine elementary matrix E such that EC = A, we need to obtain A by performing elementary row operation on C. C = [ 1 2 − 1 1 1 1 2 1 − 1 ] → R 3 → R 3 −
