Write the dual maximization problem, and then solve both the primal and dual problems with the simplex method. (For the dual problem, use x1, x2, and x3 as the variables and f as the function.) Minimize g = 6y1 + 28y2 subject to 2y1 + y2 ≥ 14 y1 + 3y2 ≥ 14 y1 + 4y2 ≥ 17 . primal g = primal y1 = primal y2 = dual f = dual x1 = dual x2 = dual x3 =
