此时a&#39,b&#39,①式无解,根据题意有n=6n'=a;=f-4;=n+1-4=n-3;=f+6;b&#39,则a&#39,代入①式;d&#39,其中n与n’皆为正整数,b为0~8,于是n&#39,①式无解,则a&#39,且a+b+f=9,于是a+b+f=36-3 x 9=9;=d+1。所以f为4~9,于是n&#39,①式无解,f&#39。考虑d,f&#39,如果d为0~8;=e-9;所以d=9,e'f&#39,d&#39,e&#39。综上所述;=e-9,d'c'b'd&#39,设其各位数字之和为n;,解得n=36;=abc,f'e'=abcde;所以e=9,新的6位数为a' ①,e'=n+1-9-4=n-12,a为1~9,则abcdef+6后无需进位,于是n&#39,f'=b+1,于是a'c'b'=f-4。以此类推;;c'=d-9考虑6位数abcdef,最终得到c=9;=c-9,原6位数abcdef为ab999f;=f-4;=n+1-9-9-9-4=n-30;=n+6,此时abcdef+6需要进位,b为0~8;c'=abcd:如果e为0~8;b&#39,于是n'd'=e+1,c&#39,其各位数字之和为n'e&#39,其中f为4~9。如果f为0~3
那么,所有这样的6位数各是多少
f=4时:,9994f=5:,409995f=6:f=7:9997f=8:109998

1+3n是5的倍数、百,而且只能是进1,十,n不大于5有:t=6(t-3-9n)5t=18(1+3n)t是整数、329994。n=3t=36据此可写出符合条件的所有数字加上6,又会进1,各位数字之和又会少9设原各位数字之和为t、419994、千都是9,十位以上9的个数为n:个位加上6有位,数字和为36509994,一定要有进位,这样各位数字之和会少3;如果十位是9
