Consider the following linear programming models: Solve them using the graphical method, justifying each procedure.

s.a = subject to

= = max 2 = 4x1 + x2 s.a. = = = min z = 4x + X2 s.a. 3x1 + x2 = 3 4x2 + 3x, 26 X1 + 2x, 54 X, 20, x, 20 3x1 + x, = 3 4x2 + 3x, 26 X1 + 2x, 54 X, 20, x, 20 min z = 4x4 + X2 s.a. 3x2 + x2
