E B E G
+ B F E G
--------------
D A D C B

its obvious that D=1 & G+G=B means B is an even number
to make D=B+F=1 possible pairs of B,F are:
B=6,F=5, with no carry (case 1)
B=4,F=6,with a carry 1 (case 2)
B=6,F=4, with a carry 1(case 3)

case 1:
D=1
F=5
B=6 means G=3
now E+E=C & remaining digits=0,2,4
possible E,C pair is only E=2,C=4
substituting B,C,D,E,F,G with their values we get A=9 (not possible as desired value A=0)

case 2:
D=1
F=6
B=4 means G=2
now E+E=C & remaining digits=0,3,5
possible E,C pair is only E=5,C=0
substituting B,C,D,E,F,G with their values we get A=0 (not possible as C is already 0, desired value A=3)

case 3:
D=1
F=4
B=6 means G=3
now E+E=C & remaining digits=0,2,5
possible E,C pair is only E=5,C=0
substituting B,C,D,E,F,G with their values we get A=2 ( Answer)
