连利y=2x-3 3x+2y=8
2分之x-3分之y=6分之5连利x-2y=-3要过程
【2(x-y)^3-8(x-y)^2(x+y)+6y(x-y)^2】/2(x-y)^2=
12y(x-y)^2-8(x-y)^3=?
(x-y) (x-2y)+(x+2y) (x-3y)-2(x-3y) (x-4y)=
(x+y)(x-y)+(x-y)平方-(x-y)(3x-y) 其中x=-2 y=3分之一
已知x-y/x+y=3,求代数式5(x-y)/x+y-x+y/2(x-y)
(x+y)(2x-3y)=?
3X+Y-6=0 与X^2+Y^2-2Y-4=0连立方程组怎么消去Y? 我要详细过程
已知x-y=3,求[(x+y)(x-y)-(x-y)^2+2y(x-y)]除以的值
已知3x =2y 求x/x+y+y/x-y-y²/x²-y²
(4x-2y-z)-{5x[8y-2y-(x+y)]-x+(3y-10z)]=? kuaihuajian
x-y/x-x+y/y-(x+y)(x-y)/y² y/x=2
若2/x-1/y=3,求[y/x-y/x-y(x-y/x-x+y)]/x-2y/x的值
9y=3x-(x-1),4(x+y)-(2x+4)=8y
3x-2y=9 x-3y=2 x+y=5 x+2y=3 y=x 2x+y=8
x+y=1 5x-2y=8 3x-y=7 2x-y=3x表示y和用y表示x
已知实数x.y满足根号(x+y-8)+根号(8-x-y)=根号(3x-y-4)+根号(x-2y+7),求x,y
