Answer :

Given : A.

To find : matrix A

Formula used :

Where c_{ij} = a_{i1}b_{1j} + a_{i2}b_{2j} + a_{i3}b_{3j} + ……………… + a_{in}b_{nj}

IF AX = B, then A = BX^{-1}

A. =

A =

To find

Determinant of given matrix = = 5(2) – (4)(3) = 10 – 12 = -2

Adjoint of matrix =

= × =

=

A = =

A = =

A = = =

A =

A =
