2 Use Simplex tableau method to solve the following linear programming problem: maximize \( f=2 x_{1}+5 x_{2}+4 x_{3} \) subject to \( x_{1}+x_{2}+2 x_{3} \leq 20 \) \( 2 x_{1}+x_{2}+x_{3} \leq 10 \) \( x_{2}-x_{3} \leq 5 \) \( \begin{aligned} 3 x_{1} &+3 x_{3} \leq 12 \\ x_{1}, x_{2}, x_{3} & \geq 0 \end{aligned} \)
