Question

Solve by cross multiplication method

8x – 3y = 12 ; 5x = 2y + 7​

Answer 1

6x + 7y - 11 = 0 ------(1)

5x + 2y - 13 = 0 ------(2)

x/(-91 + 22) = y/(-55 + 78) = 1/(12 - 35)

x/(-69) = y/(-23) = 1/(-23)

x = -69/(-23) = 3

y = -23/(-23) = 1

Hence the solution is (3, 1).

(iii) (2/x) + (3/y) = 5, (3/x) - (1/y) + 9 = 0
