Prove that if A is row-equivalent to B and B is row-equivalent to C, then A is row-equivalent to C.Getting Started: To prove that A is row-equivalent to C, you have to find elementary matrices E1, E2, . . . , Ek such that A = Ek . . . E2E1C.(i) Begin by observing that A is row-equivalent to B and B is row-equivalent to C.(ii) This means that there exist elementary matrices F1, F2, . . . , Fn and G1, G2, . . . , Gm such that A = Fn . . . F2F1B and B = Gm . . . G2G1C.(iii) Combine the matrix equations from step (ii).
