若(x-y)/(x+y)=3 则(x+2y)/(6x-7y)等于
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=4,则多项式1/2(x+y)+4(x-y)-3(x-y)-3/2(x+y)-x+y值是()
2(x+y)-3(x-y)=1 6(x+y)+(x-y)=51
{3(x+y)-4(x-y)=4 {x+y/2 + x-y/6=1
若2x-3y+4=0则x(x*x-1)+x(5-x*x)-6y+7
若2x=3y,则(x*x+y*y)/x*x=?
若x、y满足2x+y=6,x-3y=1,求7y(x-3y)²-2(3y-x)³的值
已知:2x+y=6,x-3y=1 求7y(x-3y)(x-3y)-2(3y-x)(3y-x)
若2X+3Y-1=Y-X-8=X+6则2X+Y=
若2X+3y-1=y-x-8=x+6,则2x-y=?
若X+6=Y-X-8=2X-3Y-1,则3X-Y=?
若X+6=Y-X-8=2X-3Y-1,则3X-Y=?
若5x+3y=3x+4y=x+2y+6,则x+y=___
若x,y满足|2x-y-3|+|3x+2y+1|=0,则x= y=
若x+6=y+x-8=2x-3y-1,则x-y=
若x,y满足|x-y+1|+(x+y+3)^2=0则x^2-y^2=
若x^2-y^2=6 x+y=3 则x-y=多少
