Opencv face detection program freezes when face is shown

I am using using python 3.5 and opencv 3.4.0. My program will open but it freezes after a face appears onscreen. Below is the error I get along with the code.

exec(compile(f.read(), filename, 'exec'), namespace)

File "/Users/connorwoodford/Desktop/temp.py", line 14, in cv2.rectangle(img, (x+y), (x+w, y+h), (255,0,0), 2)

SystemError: new style getargs format but argument is not a tuple

    ret, img = cap.read()
    gray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)
    faces = face_cascade.detectMultiScale(gray, 1.3, 5)
    for(x,y,w,h) in faces:
        cv2.rectangle(img, (x+y), (x+w, y+h), (255,0,0), 2)
        roi_gray = gray[y:y+h, x:x+w]
        roi_color = img[y:y+h, x:x+w]
        eyes = eye_cascade.detectMultiScale(roi_gray)
        for (ex,ey,ew,eh) in eyes:
            cv2.rectangle(roi_color, (ex, ey), (ex+ew,ey+eh), (0,255,0), 2)

    k = cv2.waitKey(30) & 0xff
    if k == 27:
