    proceed without options to learn better
    just hint

    AS D+A=D ,IT MEASN A=0
    E * W=A MEANS
    A=MUST BE A PART OF 10,20,30,0R 40
    10=2*5
    20=4*5
    30=6*5
    40=8*5
    MEANS ONE OF THEM MUST BE 5 AND OTHER WILL BE AN EVEN NUMBER
    IF W =5 THEN
    FROM MULTIPLICATION B P W
    * N
    ______
    D ….D MUST BE 0 OR 5…D CANT BE ZERO AS A IS ZERO AND D CANT BE 5 ALSO
    SO W IS NOT 5 ….E WILL BE 5…AND POSSIBLE VALUES OF W{2,4,6,8}
