Web1 In some cases, a matrix may be row reduced to more than one matrix in reduced echelon form, using a di erent sequence of row operations. False. Theorem 1 says that the RREF is unique. 2 The row reduction algorithm applies only to augmented matrices for a linear system. False. Paragraph two reads: \The algorithm applies to any matrix, WebThe leading one of a row does not have to be to the immediate right of the leading one of the previous row. A matrix in row-echelon form will have zeros below the leading ones. Gaussian Elimination places a matrix into row-echelon form, and then back substitution is required to finish finding the solutions to the system.
