若实数x,y满足x>=1,y>=1,x+y

若实数x,y满足x-y+1》=0,x+y>=0,x 若实数x,y满足x-y+1>=0,x+y>=0,x 若实数x,y满足x>=1,y>=1,x+y 已知实数x,y满足y=|x-1|若x+2y 若实数x,y满足不等式x-y>=-1,x+y>=1,3x-y 若实数x,y满足不等式x-y>=-1,x+y>=1,3x-y 若正实数x,y满足x+y+1/x+1/y=5,则x+y的最大值是多少 实数x,y满足{x-y+1>=0;y+1>=0;x+y+1 已知实数x,y满足方程x*x+y*y-4x+1=0.求y-x的最大值 实数x,y满足x^3-y^3-3xy=1,则x-y= 已知正实数x,y满足(x-1)(y+1)=16,x+y最小值是 己知实数x,y满足{ (x-y+6) (x+y-6)>=0,1 已知实数x,y满足y=|x-1|,则x+2y的最大值是 实数x,y满足y=(根号2x)+(根号1-2x),求y最大值. 已知实数x,y满足x-ay-1>=0,2x+y>=0,x 若实数xy满足x-y+1 若实数x,y是满足1 若实数x,y满足x|x|+y|y|=1,则点(x,y)到直线x+y=0的距离的取值范围是
