+ 850
_____

A) Y + 2N = Y, --> N = 0
B) T + 2E = 10 + T, --> E = 5
C) 1 + R + 2T must be > 20 because
W
+ 2 has to be > 10 in order for their to be a remainder of 1 to add
to F in order to get S. After making that observation it is just a
matter of trial and error substituting large enough values for T and R
to satisfy condition C while making sure that S = F + 1.
