若x,y满足(2x-3y)(3x+2y)≠0,求x/y要快,详细过程

若变量x,y满足约束条件{x>=-1;y>=x;3x+2y 变量x,y满足约束条件,x+y>=3,x-y>=-1,2x-y 若x,y满足|2x-y-3|+|3x+2y+1|=0,则x= y= 若线段x ,y 满足[2x-3y]*[3x+2y]=0 则x/y=? 若x,y满足|x-y+1|+(x+y+3)^2=0则x^2-y^2= 若x、y满足2x+y=6,x-3y=1,求7y(x-3y)²-2(3y-x)³的值 设变量x.y满足条件3x+2y 当x,y满足条件|x+3|+|y-2| 若实数x,y满足约束条件x-y-2=0,2y-3 若实数X,Y同时满足3x+2y=7和2x+3y=3,求x+y/x-y 若实数x,y满足不等式组｛x+y≥2 ｛2x-y≤4 ｛x-y≥0 ,则2x+3y的最小值是? 若x,y满足不等式x+y≥2,2x-y≤4,x-y≥0,则2x+3y的最小值为多少 若x,y满足不等式x+y≥2,2x-y≤4,x-y≥0,则2x+3y的最小值为多少1111 已知实数x.y满足根号(x+y-8)+根号(8-x-y)=根号(3x-y-4)+根号(x-2y+7),求x,y x(x-y)2-(y-x)3 当x,y满足----时,2(x+y)/3(x+y)的值为2/3 实数x.y满足(x-2(平方)+y(平方)=3则y/x的最大值? 设变量X,Y满足约束条件{X-Y+3>=0,X+Y>=0,-2
