\[\begin{aligned} \max\quad &z = 2x_1 + 3x_2\\ \text{s.t.}\quad&\\ &2x_1 + x_2\leq 4\\ &x_1 + 2x_2\leq 5\\ &x_1\geq 0, x_2\geq 0. \end{aligned}\]
- \( x_1 \) and \( x_2 \) of the model are replaced by \( x \) and \( y \) in the picture.
- You may need to zoom in/out the picture to show the full feasible region.
