f = w+6

p = w-3

f+w+p = 27

now make substitutions, or solve using elimination or matrices, to get

(f,p,w) = (14,5,8)

that is,

14 finger

5 palm

8 wrist

Let x be the number of bones in the wrist.Then fingers have x+6 bones and palm has x-3 bones. Altogether there are 27 so; wrist+fingers+palm=27 so x+(x+6)+(x-3)=27 so 3x+3=27 3x=24 x=8 Hence 8 bones in wrist, 8+6=14 bones in fingers and 8-3=5 bones in palm.
