列出下面方程的所有有可能的解决方法:
X - Y^4=LCM (X, Y)

一个班有30名学生, 他们坐在15个双人桌, 每个桌子做两个人。 有一半数量的女生跟男生坐。 有没有可能倒过来让一般的男生跟女生坐? 为什么?
这是原题,如果各位不是很明白我的翻译,请参考:
there are 30 students in a class. they sit at 15 double desks, each one is for two students. half of the girls sit with boys. Is it possible to make a rearrangement so that half of the boys sit with girls? why?
