There are two mistakes of this picture. First, Single Displacementshould have two different cases:AB + C = AC + B (C is a non-metal element)or AB + C =CB + A (C is a metal element). Second, Double Displacement should be AB + CD = AD+ CB, NOT AB + CD = AC + BD. This problem is so huge that you have to correct immediately in order not to fool others.
