#x = 4, y=1 #

#x+4iy = ix + y + 3 #

#=> x - y + 4iy -ix = 3 #

#=> x-y + i ( 4y - x ) = 3 #

We can write #3# as #3 + 0i #

#=> x-y + i ( 4y-x ) = 3 + 0i#

Equating the real and imaginary parts...

#x-y =3 #

#4y-x = 0 #

#4y = x #

#=> 4y-y =3 => y =1 #

#=> x = 4 #

#color(red)( x = 4 , y = 1 #
