pls help, ill rate, complete solution with simple explanation is appreciated, tq!

We can find the inverse of a matrix by row reduction. Suppose matrix A is given and we wish to find
dj1 d12
a13 bu h2 13
(1 0 0`
its inverse B = A". Then, AB = E or | a21 a2
a23 || b1 bz2 b3 =| 0 1 0
0 0 1
a31 a32
A33 b31 b32 b33
a13
1
0 0
Form the augmented matrix a21 an az3 0 1 0 and carry out row reduction so that the left
аз1 аз2 а33 00 1
´1 0 0 bu b2 b13
0 b21 b2 b23 |. The
0 0 1 b31 b32 b33,
hand side of the augmented matrix becomes a 3 × 3 identity matrix, 0
required matrix is the matrix remaining on the right hand side.
