please give parts b and c as Matlab script

Problem 3. (35 points) Xylene, styrene, toluene, and benzene are to be separated with the array of distillation columns. Molar feed rate of the mixture is 70kmol/min. Composition of the feed stream and the effluent streams are presented in the figure below. Write a script to solve and display appropriate output for the following questions. (a) Construct equations and corresponding matrix form to calculate the molar flow rate of each effluent stream, D1,B1,D2, and B2. (Write your answer on paper, separated from a MATLAB script.) (b) Create a script to calculate the molar flow rate of each effluent stream, D1,B1,D2, and B2. (c) Create a script to calculate molar flow rates of the first distillation column, D and B, and composition of D and B
