Use the simplex method to solve the linear programming problem.Maximize z = x1 + 2×2 + 4×3 + 6x4subject to: x1 + 2×2 + 3×3 + x4 ≤ 1003×1 + x2 + 2×3 + x4 ≤ 75 with x1 ≥ 0, x2 ≥ 0, x3 ≥ 0, x4 ≥ 0  

State the linear programming problem in mathematical terms, identifying the objective function and the constraints.A firm makes products A and B. Product A takes 3 hours each on machine L and machine M; product B takes 3 hours on L and 2 hours on M. Machine L can be used for 13 hours and M for 8 hours. Profit on product A is $7 and $10 on B. Maximize profit.
