Step-by-step explanation:
Equate the values on the left to like values on the right side
4
4x + 2i = 8 + yi , then
4x = 8 ⇒ x = 2
y = 2
Then x = 2, y = 2
5
- 10x + 12i = 20 + 3yi , then
- 10x = 20 ⇒ x = - 2
3y = 12 ⇒ y = 4
Then x = - 2, y = 4
6
2x - yi = 14 + 12i , then
2x = 14 ⇒ x = 7
- y = 12 ⇒ y = - 12
Then x = 7, y = - 12
7
54 - [tex]\frac{1}{7}[/tex] yi = 9x - 4i , then
9x = 54 ⇒ x = 6
- [tex]\frac{1}{7}[/tex] y = - 4 ( multiply both sides by - 7 )
y = 28
Then x = 6, y = 28
