Quadratic functions of Complex Numbers/?

Question

Find real numbers x and y such that (3x -4y) + (6x+2y)i=5i

Answer 1

For two numbers to be equal in the Complex world (dunno the exact terms in english) both they real part and theyr imaginary part must be equal, therefore -> the real parts: 3x-4y=0 and the imaginary parts: 6x+2y=5; Now we have a very easy system of 2 equations with 2 unknown numbers. (wont detail this further cos if u dunno these stuff u couldn't be making any Complex number equations).
