    In the question you can see that X+X=A and M is written as it is at last which means that there is no carry generated from X+X
    This implies A is not greater than 9 and as X+X=A thus possible values of X could be {1,2,3,4} . X will not be 5 as 5+5=10 which would generate a carry.
    Now use the possible values of X to began hit and trail on HMK×E cause it gives ANXX as a product.

    A G E
    O A T
    S O A R
    H O G
    G O T O
    G E C O I R

    See either O+1=E or O+2=E because (S+H+T can give max upto 2 as remainder.) Also O*E=O that means there are two possibilities:-
    1) Either O is 5 and E is an odd(thus O=5 and E=7 . E cannt be 6 cause O*E gives back E.)
    2) Or O is any even number and E is 6.
    But as we can see O+O+O=O which is possible if O=5. So put O=5 and E=7 and proceed.
    A G E
    5 5
    G O T O
    which is possible if A=3 and G =1. and it will give you T=8.
    (Note – every time keep updating the mapping figure and terminate the trial if conflict occurs. )
