Question

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

Answer 1

6(9x+6y)=3a+2b  i

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

Value of x from equation i

54x+36y=3a+2b

X=(3a +2b-36y) / 54  iii

Putting in equation 2

6(b{(3a +2b-36y)/54}–ay)=3b-2a

6((0.05ab+0.03b^2-0.6by)-ay)=3b-2a

0.3ab+0.18b^2-3.6by- 6ay=3b-2a

-3.6by-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=3a+2b-36y/54

X=(3a +2b-36 {( - 0.3ab-0.18b^2+3b-2a)/(3.6b+6a)})/54

X=3a+2b-1/54  (1/(3.6b+6a))(10.8ab+6.4b^2-108b+72) answer
