Question: Use the simplex method to find the optimal solution. Assume all variables are nonnegative. 1. Maximize f = 4x + y subject to 5x +

Use the simplex method to find the optimal solution. Assume all variables are nonnegative.

1. Maximize f = 4x + y subject to

5x + 2y ≤ 84

- 3x + 2y ≥ 4

2. Maximize f = x + 2y subject to

- x + 2y ≤ 60

-7x + 4y ≥ 20
