若2/3x=1/2y,则x:y=3:();若y=6,则x=()若2/3x=1/2y,则x:y=3:();若y=6,则x=()若2/3x=1/2y,则x:y=3:();若y=6,则x=()若2/3x=1
若2/3x=1/2y,则x:y=3:();若y=6,则x=()
若2/3x=1/2y,则x:y=3:();若y=6,则x=()
若2/3x=1/2y,则x:y=3:();若y=6,则x=()
若2/3x=1/2y,则x:y=3:(4);若y=6,则x=(9/2)
如果本题有什么不明白可以追问,
原题抄错了吧?!
若2/3x=1/2y,则x:y=4:(3);若y=6,则x=(8)
若2/x-1/y=3,求[y/x-y/x-y(x-y/x-x+y)]/x-2y/x的值
若(x-y)/(x+y)=3 则(x+2y)/(6x-7y)等于
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()
若2x=3y,则(x*x+y*y)/x*x=?
若x,y满足|2x-y-3|+|3x+2y+1|=0,则x= y=
若x,y满足|x-y+1|+(x+y+3)^2=0则x^2-y^2=
若变量x,y满足约束条件{x>=-1;y>=x;3x+2y
若3x-5y=0,则x+y/x=(),x-y/y=(),2x-3y/2x+3y=( )
若x+2y分之x-y=3,则代数式x+2y分之2(x-y)-3(x-y)分之x+2y的值为
若x=-1/4,能否确定代数式(2x-y)(2x+y)+(2x-y)(y-4x)+2y(y-3x)的值?
(3x-y)^2+(3x+y)(3x-y),x=1,y=-2
二元一次方程 :2(x+y)-(x-y)=3 (x+y)-2(x-y)=1
(x-y)/(x+y)=3求( 3x-2y-1)/(x+y-5)
2(x+y)-3(x-y)=1 6(x+y)+(x-y)=51
{3(x+y)-4(x-y)=4 {x+y/2 + x-y/6=1
变量x,y满足约束条件,x+y>=3,x-y>=-1,2x-y
(x-y)^2+(x+y)(x-y) 其中 X =3 Y=-1
若2x-3y+4=0则x(x*x-1)+x(5-x*x)-6y+7
