x、y满足的约束条件0

.若x、y满足约束条件 x - y +1≥0 设X,Y满足约束条件X+Y 线性规划的一道题已知变量x,y满足约束条件x+y-1=0x-y-1 满足约束条件(绝对值x)+2(绝对值y) 已知变量x,y满足约束条件1 已知x,y满足约束条件：x-y+1>=0,x+y-2>=0,x 已知x,y满足约束条件x-y+5>=0 x+y>=0 X 设x,y满足约束条件x>=0 x>=y 2x-y 设x,y满足约束条件x>=0 y>=x 4x+3y 设变量X,Y满足约束条件{X-Y+3>=0,X+Y>=0,-2 若变量x，y满足约束条件x+y≤2x≥1y≥0 若实数x,y满足约束条件x-y≥0,x+y≥0,2x+y≤1,则y/(x+1)的最大值是多少,
