xy满足约束条件x-ay-1>=0,2x+y>=0,x-1/2

xy满足约束条件x-ay-1>=0,2x+y>=0,x-1/2 xy满足约束条件x-ay-1>=0,2x+y>=0,x 已知实数xy满足约束条件x-ay-1>=0,2x+y>=0,x0,重点提供一下思路,跪谢! 已知x,y满足约束条件：x-y+1>=0,x+y-2>=0,x 已知xy满足约束条件y=2 2X+y 设xy满足约束条件x≥0,x≥y,2x-y≤1,求z=3x+2y的最大值 设xy满足约束条件 x+y>=1 x-2y>=-2 3x-2y 已知变量x,y满足约束条件x+2y-3=0,y-1 若实数xy满足约束条件x≥0 y≥0 x+y≤1 则Z=2x+y最大值为 简单线性规划问题1道题 x、y满足约束条件{2x-y>=0 2x+y>=0 x 设x,y满足约束条件x>=0 x>=y 2x-y 若变量x,y满足约束条件{x>=-1;y>=x;3x+2y
