Step-by-step explanation:

ii.

  • (x - iy)(3 + 5i)
  • 3x - 3iy + 5ix - 5i²y
  • 3x + 5y + 5ix - 3iy
  • Conjugate of -6 - 24i ⇒ -6 + 24i
  • Real part : 3x + 5y = -6
  • Imaginative part : 5x - 3y = 24

Solving

  • 9x + 15y = -18 [Multiplying the real part throughout by 3]
  • 25x - 15y = 120 [Multiplying the img part throughout by 5]
  • 34x = 102
  • x = 3
  • 27 + 15y = -18
  • 15y = -45
  • y = -3
