I would like some assistance

The following problem represents a dual maximization problem: Max Z = 8y1 + 2yz subject to y1 - y2 $ 1 y1 + 2/2 3 8 y1+ yz $ 5Answer the following questions: In the initial simplex table, (1) What is the pivot row? (1 mark) (2) What is the pivot column? (1 mark) (3) What is the pivot variable? (1 mark) (4) Determine the optimal simplex table (Show ALL workings) (7 marks) In the optimal simplex table, (5) Identify the basic variables. (1 mark) (6) Identify the non-basic variables, (1 mark) (7) Determine the optimal value for each variable and for the objective function
