某艺术学校女生的2/3与男生共682人,1/4的女生与2/5的男生相等,问该校女生有多少人?只要例综合算式

设女生为X,男生为Y
2/3X+Y=682
1/4X=2/5Y
换算一下就是
2/3X+5/8X=682

用there be ：
1.There is a art school
2.There are many people dancing
介词短语提前句首,主句完全倒装：

neither/nor/so +谓+主：
1.I like music, and they like it also.
2.We neither been to Korea, nor like Korea.
3.You know and like this writer.
至于句首是名词完全倒装,至于句首代词不倒装：
1.Let's go there.
2.They are not coming here.
用so...that.../such...that...的：
1.We are so happy that we forgot to catch the train.
2.You are such a intimate person that everyone likes you.
