If (3 x+2)-(5 y-3) i and (6 x+3)+(2 y-4) i are conjugates of each other, then the value of x-y x+y is (where i = -1 , x, y R )

Options

  1. A-1
  2. B0
  3. C1
  4. D2

Correct answer

B. 0

Step-by-step solution

(3 x+2)-(5 y-3) i and (6 x+3)+(2 y-4) i are conjugates of each other. 3 x+2=6 x+3 and 5 y-3=2 y-4 3 x=-1 and 3 y=-1 x=- 1 3 and y=- 1 3 x-y x+y =0
