In this addition probleM, each letter represents the same digit in both problem. Replace each letter with a different digit, 1 through 9, so that both additon problems a true.
ABC + DEF = GHI
ADG + BEH = CFI
There are four different solutions:
Solution 1:
ABC + DEF = GHI, ADG + BEH = CFI
146 + 583 = 729, 157 + 482 = 639
Solution 2:
ABC + DEF = GHI, ADG + BEH = CFI
157 + 482 = 639, 146 + 583 = 729
Solution 3:
ABC + DEF = GHI, ADG + BEH = CFI
718 + 236 = 954, 729 + 135 = 864
Solution 4:
ABC + DEF = GHI, ADG + BEH = CFI
729 + 135 = 864, 718 + 236 = 954
