已知x/5=y/3,则(x/x+y)+(y/x-y)-(yxy/xxx-yxy)已知x/5=y/3,则(x/x+y)+(y/x-y)-(yxy/xxx-yxy)已知x/5=y/3,则(x/x+y)+(
已知x/5=y/3,则(x/x+y)+(y/x-y)-(yxy/xxx-yxy)
已知x/5=y/3,则(x/x+y)+(y/x-y)-(yxy/xxx-yxy)
已知x/5=y/3,则(x/x+y)+(y/x-y)-(yxy/xxx-yxy)
y=3x/5
原式=x/(x+3x/5)+(3x/5)/[x-3x/5]-(9x^3/25)/(x^3-9x^3/25)
=8/3-3/2-9/16
=29/48
已知x/5=y/3,则(x/x+y)+(y/x-y)-(yxy/xxx-yxy)
已知:3x-5y=0,求x/y,x-y/y,x-y/x
已知x-y/x+y=3,求代数式5(x-y)/x+y-x+y/2(x-y)
已知3X=5Y,则X:Y=
已知x-y=3则5(x-y)-3x+3y-2=
已知x-y=3则5(x-y)-3x+3y-2=
已知5|x+y-3|+（x-y）²=0则x=,y=
已知x,y满足x+3y=5,3x+y=-1,则x-y=?
已知x*x+4x+y*y-2y+5=0,则x*x+y*y=?
已知2x=3y,则y分之x=< >,y分之x+y=< >.
1 已知1/X+1/Y=1/X+Y 则 Y/X+X/Y=2 已知1/X-1/Y=5,则3X+5XY-3Y/X-3XY-Y=
比例线段：已知x/y=2/3,则 x/x+y= ,x-y/x+y= 要过程!
已知x.x+y.y-6x-8y+25=0,求3x.x+5y的值
已知5x=7y,则x:y=( )
已知5x=4y,则x:y=():()
已知3x=8y,则x;y=?
已知|x+y-3|+(x-y)2=0则
已知实数x,y满足y=x^2+5x-4,则3x-2y最大值为
