Is the statement "two matrices are row equivalent if they have the same number of rows" true or false? explain. a. true, because two matrices that are row equivalent have the same number of solutions, which means that they have the same number of rows. b. true, because two matrices are row equivalent if they have the same number of rows and column equivalent if they have the same number of columns. c. false, because if two matrices are row equivalent it means that there exists a sequence of row operations that transforms one matrix to the other. d. false, because if two matrices are row equivalent it means that they have the same number of row solutions.
