Answer:
Step-by-step explanation:
We want to find the inverse of
To find the inverse matrix, augment it with the identity matrix and perform row operations trying to make the identity matrix to the left. Then to the right will be inverse matrix.
So, augment the matrix with identity matrix:
- Subtract row 1 multiplied by 4 from row 2
- Add row 1 multiplied by 4 to row 3
- Subtract row 2 multiplied by 2 from row 3
- Divide row 3 by −27
- Add row 3 multiplied by 2 to row 1
- Subtract row 3 multiplied by 11 from row 2
As can be seen, we have obtained the identity matrix to the left. So, we are done.
