The main idea is to prove that each row of each matrix is a linear combination of the rows of the other matrix First suppose that one of the matrices R R has one zero row Then the solutions of the corresponding system depend on 2 parameters Hence the other matrix also has a zero row and the second rows of R R coincide they are both zero    See Answer
