若3x-5y=0,则x/y=()
若3x-5y=0,则x/y=()
若3x-5y=0,则x/y=()
.
3x=5y
x/y=5/3
若3x-5y=0,则x+y/x=(),x-y/y=(),2x-3y/2x+3y=( )
(5)若x/2=y/3(y不为0)则x/y=____,x+y/y=___,y/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
若x,y互为相反数(y≠0),则2x+5+2y+3x/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
若(X×X+Y×Y)(X×X+Y×Y-5)=36,则X×X+Y×Y=
若5X-8Y=0,则X+3Y/X-3Y=
若|x+y-3|+(x-y-5)^2=0,则x)^2-y^2=
已知5|x+y-3|+(x-y)²=0则x=,y=
若实数x,y满足x的平方+y的平方-4x-2y+5=0,则(x+y)/2x-3=
若3x=5y,则x:y=________,(x-y):y=______
先化简,再求值 [2/3x - 2/x+y(x+y/3x -x-y)]*x/x-y,其中5x+3y=0
若2x-3y+4=0则x(x*x-1)+x(5-x*x)-6y+7
若|x-3|+(y+2)=0,则(x-y+4xy/x-y)(x+y-4xy/x+y)的值是
若|x-3|+(y+2)²=0,则(x-y+4xy/x-y)(x+y-4xy/x+y)的值是
若3x=7y,则y比x= ,x:(x+y)=
若|2x-y+5|+(x+2y-4)的平方=0,则(2x-y)的三次方-(x-3y)(y-2x)的平方
