The value of this determinant is found by finding the difference between the diagonally down product and the diagonally up product
now here, the equation is.
x + y = 3
3x - 2y = 4
The denominator determinant, D, is formed by taking the coefficients of x and y from the equations written in standard form.
according to formula,
D = ( 1 ) × ( -2 ) - ( 1 ) × ( 3 )
D = - 2 - 3
D = -5
