若|3/2x-6|+|0.2+2y|=0,则x=1/8打错了,呵呵,这个才对→若|3/2x-6|+|0.2+2y|=0,则x²-y²=()
若|3/2x-6|+|0.2+2y|=0,则x=1/8
打错了,呵呵,这个才对→若|3/2x-6|+|0.2+2y|=0,则x²-y²=()
若|3/2x-6|+|0.2+2y|=0,则x=1/8打错了,呵呵,这个才对→若|3/2x-6|+|0.2+2y|=0,则x²-y²=()
答 |3/2x-6|+|0.2+2y|=0,所以 |3/2x-6| 0.2+2y|,他们的值为0所以2分之3X-6=0二分之3X=6 X为9.9的平方 9*9=81.0.2+2Y=0
2Y= -0.2 Y为-0.1 -0.1的平方=0.01.81-0.01=80.99
若(x-y)/(x+y)=3 则(x+2y)/(6x-7y)等于
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=( )
【2(x-y)^3-8(x-y)^2(x+y)+6y(x-y)^2】/2(x-y)^2=
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
x^2+4y^2-6x+4y+10=0,求x^4-y^4/(x+2y)(x-2y)*x+2y/xy^2+y^3除以(x^2+y^2/y)^2的值
(5)若x/2=y/3(y不为0)则x/y=____,x+y/y=___,y/x-y=___.
若|5x-2y-3|+(x+6y-11)X(x+6y-11)=0成立,求x,y的值
若|5x-2y-3|+(x+6y-11)X(x+6y-11)=0成立,求x,y的值,
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满足2x+y=6,x-3y=1,求7y(x-3y)²-2(3y-x)³的值
若根号x+y-3+绝对值xy+x+y-2=0,求x/y+y/x根号x+y-3+绝对值xy+x+y-2=0,求x/y+y/x
化简求值:已知x、y满足:x^2+y^2-4x+6y+13=0 求代数式 的值.(3x+y)^2-3(3x-y)(x+y)-(x-3y)(x+3y)急用!
若x>0,y>0,且√x(√x+√y)=3√y(√x+5√y),求2x+2√x*√y+3y/x-√x*√y+y
若2x^2-3xy+2y^2=0,x>0,y>0,x+y/x-y
若(3x+y+6)^2+|x+y+2|=0,则x=
若|x-2|+|2y+3x-6|=0,求x,y的值.
