Question

find real numbers x and y 4x+i(3x-y) is the conjugateof 3-6i ​

Answer 1

Answer:

x = 3/4  &  y = - 15/4

Step-by-step explanation:

Conjugate of 3 - 6i = 3 + 6i

If 4x + (3x - y)i and 3 + 6i are equal:

⇒ 4x + (3x - y)i = 3 + 6i

Comparing both sides,

4x = 3     &  (3x - y) = 6

x = (3/4)  &  3(3/4) - y = 6

x = (3/4)   &  - 15/4 = y
