Weban equivalent system: 1. interchange two rows 2. multiply a row by a nonzero constant 3. add a multiple of one row to another row If any of these three operations are performed on a matrix A to obtain a matrix B, then matrices A and B are said to be row equivalent. Matrix multiplication can also be used to carry out the elementary row operation. WebProve the following converse: If A and B are two m x n matrices with Row (A) = Row (B), then A and B are row equivalent. linear algebra. Let A and B be an m × n matrices.

WebTo show interchanging a row: To multiply row 2 by : To multiply row 2 by and add it to row 1: Example 4.39 Perform the indicated operations on the augmented matrix: ⓐ Interchange rows 2 and 3. ⓑ Multiply row 2 by 5. ⓒ Multiply row 3 by and add to row 1. Try It 4.77 Perform the indicated operations sequentially on the augmented matrix: Weband hence we can switch the two rows to obtain a new row equivalent matrix where the rst position is not 0. Hence we may assume that a 6= 0. Now we may divide the rst row by a so that that we get the row equivalent matrix: 1 b=a c d Then we may subtract c times the rst row from the second row in order to obtain: 1 b=a 0 d cb=a
