The matrix equation form is .
When, .
Therefore solution matrix is .
First find the determinant of A = ad bc.
.
Therefore A-1 exists.
\The inverse of A is .
Substitute a = 3, b = 6, c = 2, d = and ad
bc =
.
.
Substitute the values of in the solution matrix
.
Multiply each side by .
The solution is .
