question 118

Short Answer

Solve the LP problems. If no optimal solution exists, indicate whether the feasible region is empty or the objective function is unbounded.
​
Minimize $c = 2 x - 2 y$ subject to
​ $\begin{aligned}\frac { x } { 6 } & \leq y \\y & \leq \frac { 2 x } { 5 } \\x + y & \geq 7 \\x + 2 y & \leq 20 \\x \geq 0 , y & \geq 0\end{aligned}$ ​
Min: $c =$ __________, $x =$ __________, $y =$ __________
