|x|=99 |y|=98 x>y x,
x-y/x-x+y/y-(x+y)(x-y)/y² y/x=2
化简 x / y(x+y) - y / x(x+y) =
x(x+y)(x-y)-y(y+x)(y-x)=(x-y)( )填空
y=x(x
x+x+x+x+y+y+y=56
x^2+y^2=15,x+y=7,x>y,求x-y
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
已知:3x-5y=0,求x/y,x-y/y,x-y/x
推倒公式:(x+y)(x*x-3x+y*y)=x*x*x+y*y*y怎么做.
已知|x|=99,|y|=98,并且x大于y.求x,y的值;若x小于y,那么x,y的值又如何呢?
x+y=5; x^y+y^x=17
X+Y=40,(X*Y)/(X+Y)=7.5
