[3x+6y = 3]
using matrix equation. If solution is not possible​

Answer 1

Answer:

i am so sorry I have no ans of this question

Answer 2

Step-by-step explanation:

let, A = 4 3 x= x B=9

3 6 y 3

(A) =4 3

3 6

(A) =24-9

=15 is not equal to zero

let c be the cofactor of Corresponding elements of matrix A

then, C = 6 -3

-3 4

now, adjoint of A = adj of A/det of A

1/15 ( 6 -3 )

( -3 4 )

therefore, x=A invrse B

X = 1/15 (6 -3) ( 9)

(-3 4) ( 3)

=1/15 (25-9)/(-27+12)

=1/15 (45)

(-15)

now, X= (3)

(-1)

hence, x=3 and y=-1 is right answer
