Question

3x + 6i = -9 + (2y)i Find x and y..?

Answer 1

`x = -3` and `y=3` assuming `x` and `y` are real.

Explanation:

The problem is underdetermined if we don't assume `x` and `y` are real.

Assuming `x` and `y` are real we can equate respective real and imaginary parts:

`3x + 6i = -9 + 2yi`

`3x = -9` and `6 = 2y`

`x = -3` and `y=3`
