Question

plz plz help!
using elementary transformations, find the inverse of the following matrix:
3 4 2
0 2 -3
1 -2 6

Answer 1

Hope you know the procedure.
If the matrix is A write it like A I, where I is identity matrix. Do the following row transformations on both the matrices simultaneously.
1. Row 1- 2 times row 3, this makes first element 1
2. Row 3 - row 1
3. row3 - row2
4. row 1+ row3 *10/19
5. row 3 / 19
6. row 2/2
7 row2 - row3
Hope this helps
