若|x-2|+|2y+3x-6|=0,求x,y的值.

若|x-2|+|2y+3x-6|=0,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+3=0,求2/3-2x-2y+(-x-y)^2 若x^2+y^2-6x+4y+13=0 求x+y 因式分解 若 x^2+4x+y^2-6y+13=0 求y^x 若2x-3y=0,求5x+4y/3x-2y 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 若x²+2x+y²-6y+10=0求x y 若／X+Y-9／+（2X-Y+3)=0求X与Y的值 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x^2+y^2-10x-6y+34=0,求（x-y)/(x+y)的值 如果|x+y+z-6|+|2x+3y-z-12|+|2x-y-z|=0求x,y, 若X,Y互为相反数,且(X+Y+3)(X-Y-2)=0,求X,Y的值? 若根号2x+y+|x平方-9| ---------------------- =0,求3x+6y的立方根.根号3-x.........根号2x+y+|x平方-9| 若 ---------------------- =0，求3x+6y的立方根.根号3-x x+y/2+ x-y/2=6 2(x+y)-3x+3y=24 求X Y x*x+2x-y*y+6y-8=0,x+y不等于2,求x-y的值 已知X*X+Y*Y+6X-8Y+25=0 求（Y/X)+(X/Y)-2=?
