1、4
2、5
3、(6a+2b)/(4a-3b)
3x(2x+y)-2x(x-y),其中x=1,y=1/5
1/2x-(x+y/2x -x-y)÷(x+y)
把(x+y),(x-y)个作为一个整体合并同类项1,7(x+y)-2(x+y)-4(x+y)+2(x+y)2,(x-y)²+2(x-y)-(x-y)-2(x-y)²
已知x-y=1,y≠0,求{(x+2y)²+(2x+y)(x+4y)-3(x+y)(x-y)}÷y的值.
求下列值域y=x^2-3x+2/x^2-1y=x^2+x+1/x^2-x+1
先化简再求值 [(x-y)²+(x+y)(x-y)]÷2x,其中x=3,y=1
y=0.5x(x+2)(3x-1) 求x轴交点.
x²/xy-x/y 3x/4x+y - x-2y/4x+y (1-y/y+x)÷x/y²-x²
化简 3x(x^2-x-1)-(x+1)(3x^-x) X^3(x-y)+x(y-x)
(2)(x-2)(x+2)-(x+1)(x-3)(3) (ab+1)²-(ab-1)²(4)(2x-y)²-4(x-y)(x+2y)
方程组 2x+3y-1=x+6 y-x-8=x+6 怎么解,
已知y=√ <2x-1> + √(3 -2x) x∈(½ ,2/3)则函数y的值域为多少?
已知x+y=-2,试计算1/2(x+y)+4(x-y)-3(x-y)-3/2(x+y)-x+y的值
设x>0y>0,x≠y,x^2-y^2=x^3-y^3,求证:1<x+y<4/3
若2x-3y+4=0则x(x*x-1)+x(5-x*x)-6y+7
.若实数x,y满足x|x|-y|y|=1,则点(x,y)到直线y=x的距离的取值范围是
3X+2Y=-1,X-3Y=7,X=?Y=?
若X>1,Y>0,且满足XY=X的Y次方,X/Y=X的3Y次方,则X+Y等于?
