Will anyone help me with PIVOTING a MATRIX?

Pivot the system about the element in row 2, column 2. Do not completely reduce the matrix. [Recall that pivoting about an entry means to make that entry a 1 and all other entries in that column zeros.]


1 -9 -5 | -4

[ 0 -2 -4 | 7 ]

0 -9 1 | -9


i would appreciate your time, i have been stuck trying to comprehend this for hours. so far the only right answers i have are as shown below, where "_" are the numbers I cannot reach yet.


1 0 _ | _

[ 0 1 _ | _ ]

0 0 _ | _


Thank you!
