To identify: the elementary row operations performed to obtain the new row equivalent matrix.
Answer to Problem 29E
The elementary row operations performed to obtain the new row equivalent matrix are
Explanation of Solution
Given information:
The given matrix is
Calculation:
Let us consider the following row-equivalent matrices
Original Matrix
New row equivalent Matrix
Two matrices are called row equivalent if one of the matrices can be obtained from the other by a sequence of elementary row operations.
Solve the above matrix further by using row operations as
Hence, the elementary row operations performed to obtain the new row equivalent matrix are
And in words, we say “ interchange Row 1 and Row 2” and “Add 4 times new Row 1 to Row 3”.
