若x-y/y=0.5,则x/y=()若x-y/y=0.5,则x/y=()若x-y/y=0.5,则x/y=()x-y/y=0.5/1(x-y+y)/y=(0.5+1)/1x/y=1.5x/y-1=0.5
若x-y/y=0.5,则x/y=( )
若x-y/y=0.5,则x/y=( )
若x-y/y=0.5,则x/y=( )
x-y/y=0.5/1
(x-y+y)/y=(0.5+1)/1
x/y=1.5
x/y-1=0.5
x/y=1.5
x-y/y=0.5得x/y-y/y=0.5,x/y=1.5
1.5 x-y/y=x/y-1=0.5 x/y=1.5
若(X×X+Y×Y)(X×X+Y×Y-5)=36,则X×X+Y×Y=
若3x-5y=0,则x+y/x=(),x-y/y=(),2x-3y/2x+3y=( )
若x+y=4,则多项式1/2(x+y)+4(x-y)-3(x-y)-3/2(x+y)-x+y值是()
(5)若x/2=y/3(y不为0)则x/y=____,x+y/y=___,y/x-y=___.
若3x=7y,则y比x= ,x:(x+y)=
若x-y/y=0.5,则x/y=( )
若x-y不等于0,2x-3y=0,则分式(10x-11y)/(x-y)的值是()?(10x-11y)/(x-y) =[(8x-8y)+(2x-3y)]/(x-y) =8为什么8X-8Y=8?(10x-11y)/(x-y)=[(8x-8y)+(2x-3y)]/(x-y)=8+(2x-3y)]/(x-y)=8+0=8
x-y/x-x+y/y-(x+y)(x-y)/y² y/x=2
若f(x+y,y/x)=x^2-y^2,则F(X,Y)=
若(x-y)/(x+y)=3 则(x+2y)/(6x-7y)等于
x(x-2y)=y(2y-x) ,则y分之x是多少
化简 x / y(x+y) - y / x(x+y) =
若(5x+y)/(7x+10y)=1/2则x/y=
若2x-y=2y-x+15,则x-y=( )
x-y/13=y/7 x+y/y已知(x-y)/13=y/7则(X+Y)/Y=?
若3x=5y,则x:y=________,(x-y):y=______
x(x+y)(x-y)-y(y+x)(y-x)=(x-y)( )填空
若x:y=3则x:(x+y)=
