First, we write all possible (different) assignments of values from the set {1,2,...,9} for the expression: x+y+z=13. These are: 1+3+9, 1+4+8, 1+5+7, 2+3+8, 2+4+7, 2+5+6 and 3+4+6.
Then, we look for the right combination by backtracking until we find the right solution, which is: 9+3+1=1+8+4=4+7+2=2+5+6 so, A=9, E=4, I=6.
