Question

An exercises 4-7, find the values of X and Y to satisfy the equation​

Answer 1

4x + 2i = 8 + yi , then

4x = 8 ⇒ x = 2

y = 2

Then x = 2, y = 2

Answer 2

see explanation

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 -
`(1)/(7)` yi = 9x - 4i , then

9x = 54 ⇒ x = 6

-
`(1)/(7)` y = - 4 ( multiply both sides by - 7 )

y = 28

Then x = 6, y = 28
