This is about imaginary numbers, I'm supposed to find the values of x and y. The problem is x+69i=34-3yi
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
x + 69i = 34 - 3yi implies that
x = 34 and
69 = -3y.
Therefore the answer is x = 34, y = = -23.
Two complex numbers are equal if and only if their real parts are equal and their imaginary parts are equal.
This is a DEFINITION of equality of complex numbers.
