Answer:

How to Find the Inverse of 3 x 3 Matrix?

Compute the determinant of the given matrix.

Calculate the determinant of 2×2 minor matrices.

Formulate the matrix of cofactors.

Take the transpose of the cofactor matrix to get the adjugate matrix.

Finally, divide each term of the adjugate matrix by the determinant.
