若x,y满足约束条件,x>=0,y>=0,x-y>=-1,3x+4y

设x,y满足约束条件x>=0 y>=x 4x+3y 已知x,y满足约束条件：x-y+1>=0,x+y-2>=0,x 若变量x,y满足约束条件{x>=-1;y>=x;3x+2y 若实数x,y满足约束条件x-y-2=0,2y-3 已知变量x,y满足约束条件x+2y-3=0,y-1 设变量X,Y满足约束条件{X-Y+3>=0,X+Y>=0,-2 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 .若x、y满足约束条件 x - y +1≥0 设xy满足约束条件x>=0 y>=0 4x+3y=0 若x y满足约束条件｛x-y+1>=0 x+y-3=0}则z=3x-y的最小值 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
