Find the inverse of the matrix (if it exists). (If the answer does not exist, enter DNE in any cell of the matrix.)

Step-by-step explanation:

This is the formula we will use. Accordingly:

det represents the determinant

if the determinant is 0 then only the inverse matrix will not exist. So let's find the determinant.

Now we multiply the following matrix by 1/1:

answer is x<

the answer is d
