This material will not appear on the exam. We used the simplex method for finding a maximum of an objective function. Step 2: Divide each number in the quantity column by the corresponding number in the X 1 column: 100/2 = 50 for the first row and 240/4 = 60 for the second row. simplex method moves from one better solution to another until the best one is found, and then it stops. 2x + 2y = 6 2 x + 2 y = 6 , x + 2y > 9 x + 2 y > 9. The simplex method begins at a corner point where all the main variables, the variables that have symbols such as \(x_1\), \(x_2\), \(x_3\) etc., are zero.

What type of special case is this problem? Explain? The manual solution of a linear programming model using the simplex method can be a lengthy and tedious process.Years ago, manual application of the simplex method was the only means for solving a linear programming problem. It is a matrix based method used for solving linear programming problems with many variables (link.) The simplex method provides a systematic search so that the objective function increases (in the case of maximisation) progressively until the basic feasible solution has been identified where the objective function is maximised. It provides us with an iterative technique of examining the vertices of the feasible region that is not optimal, but serves as a starting point (Sirug, 2012).
