Elementary matrix is constructed out of identity for gaussian elimination, it's easier to see it on an example:
if A =
1 2 3
4 5 6
7 8 9
and E
1 0 0
-4 1 0
0 0 1
then EA =
1 2 3
0 -3 -6
7 8 9
so now the problem asks how are rows of EM related to the rows of M if E is
1 1 1
0 0 0
where M is arbitrary any matrix.
thank you in advance.
