若4x+3y+5=0,则3(8y-x)-5(x+6y-2)的值等于
若4x+3y+5=0,则3(8y-x)-5(x+6y-2)的值等于
若4x+3y+5=0,则3(8y-x)-5(x+6y-2)的值等于
4X+3Y+5=0
4X+3Y=-5
3(8Y-X)-5(X+6Y-2)
=24Y-3X-5X-30Y+10
=-8X-6Y+10
=-2(4X+3Y)+10
=-2*(-5)+10
=20
=-10
若5X-8Y=0,则X+3Y/X-3Y=
若2x-3y+4=0则x(x*x-1)+x(5-x*x)-6y+7
若3x-5y=0,则x+y/x=(),x-y/y=(),2x-3y/2x+3y=( )
若|2x-y+5|+(x+2y-4)的平方=0,则(2x-y)的三次方-(x-3y)(y-2x)的平方
(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
若x-y不等于0,2x-3y=0,则分式(10x-11y)/(x-y)的值是()?(10x-11y)/(x-y) =[(8x-8y)+(2x-3y)]/(x-y) =8为什么8X-8Y=8?(10x-11y)/(x-y)=[(8x-8y)+(2x-3y)]/(x-y)=8+(2x-3y)]/(x-y)=8+0=8
{x+y=1 ,xy=-6{x(2x-3)=0,y=x²-1{(3x+4y-3)(3x+4y+3)=0,3x+2y=5{(x-y+2)(x+y)=0,x²+y²=8{(x+y)((x+y-1)=0,(x-y)(x-y-1)=0
(5)若x/2=y/3(y不为0)则x/y=____,x+y/y=___,y/x-y=___.
若4x-3y=0(y不等于0)则x+y/y=
若5x+3y=3x+4y=x+2y+6,则x+y=___
分式 4y-3x+0 ,则(x+y):y=若 4y-3x+0 ,则(x+y):y=若 4y-3x=0 ,则(x+y):y=
若x/y=4/3 则3x+2y/2x-5y=
若|x+y-3|+(x-y-5)^2=0,则x)^2-y^2=
若2x-3y=0,求5x+4y/3x-2y
若x+y=-1,则x^4+5x^3y+x^2y+8x^2y^2+xy^2+5xy^3+y^4=( )若x+y=-1,则x^4+5x^3y+x^2y+8x^2y^2+xy^2+5xy^3+y^4=( )
若x,y满足约束条件x-y+5≥0,x+y≥0,x≤3,则z=4x-y的最小值为?具体过程
若实数x,y满足x的平方+y的平方-4x-2y+5=0,则(x+y)/2x-3=
