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
