Separate the equation into the real parts and imaginary parts. For imaginary parts, ignore the i.
Equation 1 (real parts only): -2x -4 =3x ---> -4 = 5x ---> -4/5 = x
Equation 2 (imaginary parts only, ignoring the i): 2y = -2 ---> y=-1
Plug those back into the original equation to prove they work. They do.
