Answer:
The inverse of the matrix A is
Step-by-step explanation:
We have the following matrix
Step 1 - Adjoin the identity matrix to the given matrix
Step 2 - Transform the matrix to the reduced row echelon form
- Row Operation 1: multiply the 1st row by 1/2
- Row Operation 2: add -1 times the 1st row to the 2nd row
- Row Operation 3: add -1 times the 1st row to the 3rd row
- Row Operation 4: multiply the 2nd row by 2/3
- Row Operation 5: add -1/2 times the 2nd row to the 3rd row
- Row Operation 6: multiply the 3rd row by 3/4
- Row Operation 7: add -1/3 times the 3rd row to the 2nd row
- Row Operation 8: add -1/2 times the 3rd row to the 1st row
- Row Operation 9: add -1/2 times the 2nd row to the 1st row
As can be seen, we have obtained the identity matrix to the left. So, we are done.
The inverse of the matrix A is
