48/x+y +8/x-y=1024/x+y+14/x-y=14求这两个联立方程.怎么解,
48/x+y +8/x-y=10
24/x+y+14/x-y=14
求这两个联立方程.怎么解,

48/x+y +8/x-y=1024/x+y+14/x-y=14求这两个联立方程.怎么解,
设1/(x+y)=a,1/(x-y)=b
原方程组化为:
48a+8b=10
24a+14b=14
解得:
a=7/120,b=9/10
所以
x+y=120/7
x-y=10/9
解得:
x=575/63
y=505/73

48/(x+y) +8/(x-y)=10……①
24/(x+y)+14/(x-y)=14 ……②
①-②*2
X-Y=10/9 ……③
①*7-②*4
X+Y=120/7……④
然后③④联系解出X。。Y。。

自己多动脑
