Check out the very related question Faster implementation of verbal arithmetic in Prolog.
Based on my previous answer, let's solve your specific equation using clpfd!
?- Eq = ([P,Y,P] + [C,Q,B] + [C,B,C,W] #= [W,X,Y,P,B]),
crypt_arith_(Eq,Zs),
labeling([],Zs).
Eq = ([9,3,9]+[8,7,5]+[8,5,8,1]#=[1,0,3,9,5]),
Zs = [9,3,8,7,5,1,0],
P = 9,
Y = 3,
C = 8,
Q = 7,
B = 5,
W = 1,
X = 0 ;
false.
