Use the algebraic method to solve the following optimisation problem. Maximise f(x1, x2) = 3x1+ 2x2 subject to: x1 + x2 < 5, -x1+ 2x2 < 4, 21, 22 > 0. In your answer you must: • Write down the initial augmented matrix and the subsequent ma- trices from which you obtain the basic solutions. • Find all of the basic solutions. State which of the basic solutions are feasible and which are not with a reason. • Show how you obtain the maximum of f.

Use the algebraic method to solve the following optimisation problem.
Maximise f(x1, x2) = 3x1+ 2x2 subject to:
x1 + x2 < 5,
-x1+ 2x2 < 4,
X1, 22 > 0.
In your answer you must:
• Write down the initial augmented matrix and the subsequent ma-
trices from which you obtain the basic solutions.
• Find all of the basic solutions.
• State which of the basic solutions are feasible and which are not
with a reason.
• Show how you obtain the maximum of f.
