each letter represents the same digit in both problems replace each letter with a different digit, 1 through 9, so that both addition problems are true. there are 2 possible answers.

remember the letters represents a number.

on both sides.

ABC

+DEF

----------

GHI

ADG

+BEH

------------

CFI

So for example if you choose the letter A = 1 in the first question, it should also =1 in the second question

Good luck >.<

[Prof. Templeton]

A=1

B=4

C=6

D=5

E=8

F=3

G=7

H=2

I=9

I think theres more than 1 possible answer.

This is another solution:

718

236

954

So: 718+236=954

And: 729+135=864

[Prof. Templeton]

A=1

B=5

C=7

D=4

E=8

F=2

G=6

H=3

I=9

OR

A=7

B=2

C=9

D=1

E=3

F=5

G=8

H=6

I=4

I think there are only four solutions.
