(x-5y)/(y-2x)=3,则y:x=(x-5y)/(y-2x)=3,则y:x=(x-5y)/(y-2x)=3,则y:x=(x-5y)/(y-2x)=3∴x-5y=3y-6xx+6x=3y+5y7
(x-5y)/(y-2x)=3,则y:x=
(x-5y)/(y-2x)=3,则y:x=
(x-5y)/(y-2x)=3,则y:x=
(x-5y)/(y-2x)=3
∴x-5y=3y-6x
x+6x=3y+5y
7x=8y
y:x=7:8

(x-5y)/(y-2x)=3
(x-5y)=3(y-2x)
x-5y=3y-6x
x+6x=3y+5y
7x=8y
7/8=y/x
即y:x=7:8
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=___.
已知x-y/x+y=3,求代数式5(x-y)/x+y-x+y/2(x-y)
(x-5y)/(y-2x)=3,则y:x=
x-y/x-x+y/y-(x+y)(x-y)/y² y/x=2
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()
已知方程组{(X+Y)-3(X-Y)=7,2(X+Y)+(X-Y)=-7}则(X+Y)(X-Y)=
若x-y分之x+y=3,求式子x+y分之5(x-y)—2(x-y)分之x+y的值
(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
x+y/2+x-y/6=5 2(x+y)-3(x-y)=-2
已知x/5=y/3,则(x/x+y)+(y/x-y)-(yxy/xxx-yxy)
(x-y)^3×(y-x)^4+(x-y)^2×(y-x)^5
3(x+y)+2(x-y)=36 4(x+y)-5(x-y)=2
x(x-2y)=y(2y-x) ,则y分之x是多少
(x-y)/(x+y)=3求( 3x-2y-1)/(x+y-5)
4(x-y)-3(x-y)=9 5(x-y)+2(x-y)=11
