The nine letters A through I have the integer values 1 through 9, subject to the equations below.

Can you determine the unique integer value of each letter?

        A + B = 9         B + C = 10
        C + D = 9         D + E = 10
        E + F = 9         F + G = 10
        G + H = 9         H + I = 10

Solution to the Problem:

A = 5       B = 4       C = 6
D = 3       E = 7       F = 2
G = 8       H = 1       I = 9

Since the eight letters in the left column of the puzzle add up to 36, the only missing letter (I) must equal 9 in order to make the sum of the numbers from 1 through 9 equal to 45.   Since H + I = 10, H must equal 1, and so on   ( Or you can determine, by looking at the right column that A = 5 and continue from there).
