find the inverse matrix. show all your work

-4 4 3

Solution

Your matrix

Determinant is not zero, therefore inverse matrix exists

Write the augmented matrix

Make the pivot in the 1st column by dividing the 1st row by 3

Eliminate the 1st column

Make the pivot in the 2nd column by dividing the 2nd row by 2/3

Eliminate the 2nd column

Make the pivot in the 3rd column by dividing the 3rd row by -11

Eliminate the 3rd column

There is the inverse matrix on the right

Result:

(answer)
