The system equations are
\ Equation (1)
Equation (2)
The matrix equation form is .
When, .
Therefore solution matrix is .
First find the determinant of A = ad bc.
Product of two same sings is positive.
\.
Therefore A-1 exists.
\The inverse of A is .
Substitute a = 4, b = , c = 2, d = 3 and ad
bc = 14.
.
Substitute the values of in the solution matrix
.
Multiply each side by .
The solution is .
