Solve the optimization problem using Lagrange and Coordinate Descent

Qn = 633, D1 = 4,74, D2 = 4,42, Qp = 500, Qi = 500;

Qn = 812, D1 = 6,65, D2 = 6,80, Qp = 800, Qi = 700;

Qn = 1010, D1 = 8,06, D2 = 7,53, Qp = 900, Qi = 600;

Qn = 1250, D1 = 8,13, D2 = 7,74, Qp = 1100, Qi = 600;

Qs = 2400

I want the calculations done step by step and the demonstrations if necessary through graphs and tables
