Question:
This problem deals with the reversibility of elementary row operations.
(a) If the elementary row operation cRp changes the matrix A to the matrix B, show that (1/c) Rp changes B to A.
(b) If SWAP(Rp,Rq) changes A to B, show that SWAP(Rp,Rq) also changes B to A.
(c) If cRp + Rq changes A to B, show that (-c)Rp + Rq changes B to A.
(d) Conclude that if A can be transformed into B by a finite sequence of elementary row operations, then B can similarly be transformed into A.
