|2x-1|=-|3y-6| 则（xy)=
|2x-1|=-|3y-6| 则（xy)=

|2x-1|=-|3y-6| 则（xy)=
|2x-1|=-|3y-6|
|2x-1|＋|3y-6| =0
2x－1=0, 3y－6=0
x=½, y=2
xy=1

|2x-1|=-|3y-6|
∵绝对值非负
∴2x-1=0，3y-6=0
所以x=0.5，y=0.5
xy=0.5×0.5=0.25

x=1/2
y=2
xy=1/2*2=1

已知1/x=1/y=6,则3x-2xy+3y/3xy+x+y=?已知1/x+1/y=6,则3x-2xy+3y/3xy+x+y=? 已知1/X+1/Y=6,则3X-2XY+3y/3XY+X+Y=多少 已知2/X-1/Y=3,则(X-2Y-XY)/(5XY+6Y-3X)=? 已知2/x-1/y=3,则(2y-x+4xy)/(3x-6y-5xy)=? 已知xy/x+y=1/2,则代数式3x-5xy+3y/-x+3xy-y= 已知1/x-1/y=2,求3x+7xy-3y/2x-3xy-2y答案是1/x-1/y=2(y-x)/xy=2 得：x-y=-2xy(3x+7xy-3y)/(2x-3xy-2y)=[3(x-y)+7xy]/[2(x-y)-3xy]=(-6xy+7xy)/(-4xy-3xy)=xy/(-7xy)=-1/7 谁能帮我解释一下=[3(x-y)+7xy]/[2(x-y)-3xy]=(-6xy+7xy)/(-4xy-3xy) 是怎 若x-y=4,xy=1,则(2x+y-2xy)-(3x+2y+xy)-(4xy+3y-5x)= 4xy-[(x²+5xy-y²)-(3xy-1/2y)]x=3,y=-6 化简求值x-4y/2x-7xy+3y×x-2xy-3y/2x+3xy-2y÷3x-6y/4x-4xy+y,其中：x=1999,y=-1 已知x+y=6,xy=-3,则x^2y+xy^2=? 已知x+y=6,xy=-3,则x∧y+xy∧2= |2x-1|=-|3y-6| 则（xy)= x*x+xy=3,xy+y*y=2,则x*x+2xy+y*y=________? [6xy-3(xy-1/2x的平方y]/3xy=? [6xy-3(xy-2分之1x^2y]除3xy,其中x=2002,y=2003 [6xy-3(xy-1/2x的平方y]/3xy=?其中x=2008,y=2009 已知x+y=1,xy=-2,则x²y+xy²-2xy 1-2/x+y=xy,4y+6x=xy.求xy的解?
