2x:3=x:72(y/3-1)=4(y/3-1)-12x:3=x:72(y/3-1)=4(y/3-1)-1 2x:3=x:72(y/3-1)=4(y/3-1)-1
2x:3=x:7 2(y/3-1)=4(y/3-1)-1
2x:3=x:7 2(y/3-1)=4(y/3-1)-1
2x:3=x:7 2(y/3-1)=4(y/3-1)-1
-(5x+y)-7(x-y) -2分之1(x+y)+4分之1(x+2y) 4x-2(x-2) -2x-(3x-1) x-(5x-2y)+2(2x-y)
已知x-y=1,y≠0,求{(x+2y)²+(2x+y)(x+4y)-3(x+y)(x-y)}÷y的值.
在线等先化简、在求值(x/y-y/x)除以【|x/y+y/(x)-2】除以|【|1+y/(x)】其中x=1/2,y=1 /先化简、在求值(x/y-y/x)除以【|x/y+y/(x)-2】除以|【|1+y/(x)】其中x=1/2,y=1/3
x²/xy-x/y 3x/4x+y - x-2y/4x+y (1-y/y+x)÷x/y²-x²
试说明(4x*x-7X+6Y--1)-(-2x*x+3y*y+2Y+2X)+(-6X*X+9X-Y)的值于X无关.
计算:1/(x-y)-1/(x+y)-2y/(x^2+y^2)-4y^3/(x^4+y^4)-8x^7/(x^8+y^8)
好的加更多分解方程 2X+Y=7 3X-4Y=5 3X+Y=1 X-2Y+1=0 2X-3Y=7 4X+5Y=3
去括号并合并同类项(1)3x-2(x+7)+2(2x+5) (2)(4x-3y)-[-(3y-x)+(x-y)]-5x
(x/x+y +2y/x+y)乘以xy/ x+2y除以(1/x+1/y)(2)(3x^2/4y)^2乘以2y/3x+ x^2/2y^2除以2y^2/x
已知X=11Y,(X-2)*3=Y,(X-4)*5=Y,(X-6)*7=Y,(X-8)*9=Y ,求X、Y各是多少?
整式加减2(x-2y)² -4(x-2y)+(x-2y)² -3(x-2y) 其中 x=-1,y=2分之1
若2x-3y+4=0则x(x*x-1)+x(5-x*x)-6y+7
用加减消元法:解方程组:(1)x+y=4 2x−y=5 (2)3x+2y=7x+2y=5(3)2x+y=-2x-3y=6(4)5x-3y=24y+2x=6
计算 x-2分之x方+1-2-x分之3-4x (x+y)x方-y方分之x方+y-x分之y方
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
1.(x^3-x^2-4x+1)/(x^2-3x+2)-(x^3-2x^2-9x+21)/(x^2-5x+6)+(x^2-3x+8)/(x^2-4x+3)2.{(x^2)/(x-y)}*{y/(x+y)}-{(x^4y)/(x^4-y^4)}÷{(x^2/x^2+y^2)^2}
已知(x+y)2 =2,(x-y)3 =3,求(x+y)7(x-y)2(x+y)3(y-x)4 的值
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()
