Thank you. Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! determinant = 1/ad-bc
=1/6
inverse is
-3 === 0 * 1/6
6 === -2
-1/2== 0 INVERSE
-1 ===-1/3
A ;; B ;;; D ;; -B
C ;; D ;;; -C ;; A , EACH OF THESE LATTER IS MULTIPLIED BY THE DETERMINANT 1/AD-BC IN THE ORIGINAL MATRIX.
