不妨令b=6，若d=3，則a=3，矛盾；若e=3，則c=3，矛盾。故可

不妨令b=6，若d=3，則a=3，矛盾；若e=3，則c=3，矛盾。故可判斷出g=3，此時由題意可知有以下這一組解：

ผลลัพธ์ (อังกฤษ) 1:

May b=6, d=3, a=3, paradoxically, if e=3, then c=3 and contradictions. You can figure out what g=3, meaning that there are solutions to this:

ผลลัพธ์ (อังกฤษ) 2:

May wish to make b = 6, if d = 3, then a = 3, contradiction; if e = 3, then c = 3, a contradiction. It can determine the g = 3, this time from the meaning of the questions shows that this group has the following solution:

ผลลัพธ์ (อังกฤษ) 3:

Might as well made b=6, if d=3, then a=3, contradictory; If e=3, then c=3, contradictory. Therefore may judge g=3, at this time may know the following this group of solutions by topic Italy:
