我从一本英文书看到一条数学题,inheritance share son of x inheritance equally 1st son x = 1 + 1/7 (E - 1)2nd son x = 2 + 1/7 (E - 2 - x )equal two share 1 + 1/7 ( E - 1 ) = 2 + 1/7 (E - 2 - x)1 + E/7 - 1/7 = 2+ E/7 - 2/7 - x/7x/7 = 6/7 x
我从一本英文书看到一条数学题,
inheritance
share son of x inheritance equally
1st son
x = 1 + 1/7 (E - 1)
2nd son
x = 2 + 1/7 (E - 2 - x )
equal two share
1 + 1/7 ( E - 1 ) = 2 + 1/7 (E - 2 - x)
1 + E/7 - 1/7 = 2+ E/7 - 2/7 - x/7
x/7 = 6/7
x = 6
6 = 1 + 1/7 ( E - 1)
E = 36
我从一本英文书看到一条数学题,inheritance share son of x inheritance equally 1st son x = 1 + 1/7 (E - 1)2nd son x = 2 + 1/7 (E - 2 - x )equal two share 1 + 1/7 ( E - 1 ) = 2 + 1/7 (E - 2 - x)1 + E/7 - 1/7 = 2+ E/7 - 2/7 - x/7x/7 = 6/7 x
这是类似逆推的题!E是总数!X是等分量!题的大意是第一子分得总数少一的一半多一个!第二子分剩余的减一的一半多一个!但分得的数目相等!求总数有多少
挺复杂的。
