Answer :

The given matrix equation is :-



Let A = and B =


So, we can write the equation as


AP = B


Pre-multiplying A-1 both sides we get,


A-1AP = A-1B


IP = A-1B ( A-1A = I )


P = A-1B ( IP = P ) …….(i)


Now,


|A| = = 1


and


adj A =


A-1 = adj A


A-1 =


From (i) ,


=


=


Comparing both sides we get,
