Answer by scott8148(6628)   (Show Source):
You can put this solution on YOUR website! there is no carry from the hundreds column to the thousands column , so A is less than 4
three times D is a number with A in the ones place
___ three times 1 is 3
___ three times 4 is 12
___ three times 7 is 21
if A equaled 3 ; then D would equal 1 and N would equal 9
____ but this would result in a carry from the tens column to the hundreds column , and a carry to the thousands column
if A equaled 2 ; then D would equal 4 and N would be at least 6
___ this works with N equal to 7 , and B equal to 6
if A equaled 1 ; then D would equal 7 and N would be at least 3
___ N must equal 5 for the sum of the tens column and the carry and sum of the hundreds column to fit
___ BUT , this leaves B equal to 1 (the same as A)
so the second scenario is the one you want
