360/(x+y)+360/(x-y)=35 360/(x+y)=360+(x-y)=5 y
360/(x+y)+360/(x-y)=35 360/(x+y)=360+(x-y)=5 y
360/(x+y)+360/(x-y)=35 360/(x+y)=360+(x-y)=5 y
不知道你第二个式子是不是打错了.不过不管怎样,这一类的题目解题方法很明显.
首先另x+y=a x-y=b 代入接触a,b.然后再把a,b的答案代回x+y=a x-y=b,连列,解出x,y即可.
方法就是这样.
不要只要求直接给的答案.给你思路,你就会知道怎么解了,很简单的,加油!
把题目写清楚了啊，貌似不对
360/(x+y)+360/(x-y)=35 360/(x+y)=360+(x-y)=5 y
x-y/x-x+y/y-(x+y)(x-y)/y² y/x=2
60x+120y=360 x、y等于?
化简 x / y(x+y) - y / x(x+y) =

[跪求]x+y+(x-y)=360,X与Y的解分别是多少?T_T
x(x+y)(x-y)-y(y+x)(y-x)=(x-y)( )填空
x+x+y+y+y=21 ,x+x+y+y+y+y+y=27 ,x ,y=?
x+x+y+y+y=21 ,x+x+y+y+y+y+y=27 ,x ,y=?

x+x+x+y+y=6.4 y+y+y+x+x=7.1 怎么算?
二元函数f(x,y)=x+y/x-y,求f(y/x,x/y)
x-y/x+y=(x-y)²/x²-y²（x≠y)
（x+y-5)*（x+y-5)+（x-y+3)=0 x*x-y*y
