Solve the LP problem. If no optimal solution exists, indicate whether the feasible region is empty or the objective function is unbounded. (Enter EMPTY if the region is empty. Enter UNBOUNDED if the function is unbounded.) Maximize px + 2y subject to P- (x,y) x+5ys 18 3x + y 12 x0, y 0. X Your answer cannot be understood or graded. More Information
