    we have that

    if the expression is  (x + yi) + (4 + 9) = 9 -4i
    x+13=9———–> x=9-13————-> x=-4
    yi=-4i———– > y=-4

    the solution is
    x=-4
    y=-4

    if the expression has a typing error and it is really (x + yi) + (4 + 9i) = 9 -4i
    then
    x+4=9————> x=9-4——-< x=5
    y+9=-4————-> y=-4-9 ————> y=-13
    the solution is
    x=5
    y=-13
