The matrix is .

Rewrite matrix is A =  .

First find the determinant of  A = ad bc.

.

Therefore A^-1 exists.

The inverse of A is .

Substitute a = 8, b = 5, c = 3, d = 2 and ad bc = 1.

Product of two same sings is positive.

.

CHECK:-

Find the product of the matrices.if the product is I, then they are inverses.

.

The solution is true.

The inverse matrix is .
