Question

Find the real numbers x and y that make the equation true.
-4 + yi = x + 3i

Answer 1

if x=-4 then x is ?
if yi=3i then y is?

Answer 2

for example
if a+bi=c+di
then we have a=c which means a is c
and we have bi=di which means b=d or b is d

Answer 3

so they swap positions its actually -4 +3i = -4+ 3i

Answer 4

can you say what x and y are?
like what is in place of x and what is in place of y?
