Put y=1,we get 3y=x-4 or,3 = x - 4 or, x =7.   Similarly put y=2, 3 and find x. The values of x are .....

Equating corresponding elements, we get, x + 3 = y - 2 x = y - 2 - 3 x = y - 5 -------------------- [ I ] Again, y + 4x = 2x - 1 y + 4x - 2x + 1 = 0 y + 2x + 1 = 0 Placing the value of x from equation [ I ] , we get, y + 2( y - 5 ) + 1 = 0 y + 2y - .....

Equating corresponding elements, we get, 2x = y y = 2x --------------- [ I ] Again, x+y = 9 Placing the value of y, we get, x + 2x = 9 3x = 9 x = 9 / 3 x = 3 Then, equation [ I ]  becomes, y = 2x y = 2 * 3 y = 6 Hence, x = 3, y = .....
