Question

To solve x + y =3 , 3x-2y=0 by determinant method , find D​

Answer 1

Answer:

-5

Step-by-step explanation:

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.

D =

according to formula,

D = ( 1 ) × ( -2 ) - ( 1 ) × ( 3 )

D = - 2 - 3

D = -5

Answer 2

Answer:

what is d

Step-by-step explanation:

i think the X is 2 and y is 3 because

3*2=6-2*3=6

6-6=0
