Question

6 (9x+6y) = 3a + 2b ; 6 ( bx - ay ) = 3b - 2a solve for x and y ​

Answer 1

Answer:

1. 6(9x+6y)=3a+2b

2. 6(bx-ay) =3b-2a

Value of x from equation 1

54x+36y=3a+2b

x=(3a+2b-36y)/54

Putting in equation 2

6(b((3a+2b-36y)/54)-ay) =3b-2a

6((0.05ab+0.03b

2-3.6by-6ay=3b-2a

-3.by-6ay=-0.3ab-0.18b

2+3b-2a

Y=(-0.3ab-0.18b

2+3b-2a)/(3.6b+6a)answer

Value of y in equation 3

x=3a2b-36y/54

x=(3a+2b-36((-0.3ab-0.18b

2+3b-2a)/(306b+6a))/54

x=3a+2b-1/54(1/(3.6b+6a))(10.8ab+6.4b

2-108b+72)answer
