please read the question carefully, NOTE that values for m and x2 ARE NOT GIVEN, therefore, I only need process on how to solve them if values were given.

Only part 3 needs to be answered, part 1 and 2 are already solved on my end. THANK YOU. ONLY PART 3

Q.II: A distillation column is a process unit in which a feed mixture of liquids is m2(kg A/h) separated by multiple partial vaporizations and condensations to form two or more m(kg/h) product streams. The overhead product 0.03 kg B/kg 0.97 kg C/kg stream (distillate) is rich in the most volatile 1200 kg/h components of the feed mixture, and the 0.70 kg A/kg y4(kg B/kg) bottom product stream (bottoms) is rich in z4(kg C/kg) the least volatile components (see process 5300 kg/h x2(kg A/kg) flow diagram). yz(kg B/kg) 1. How many independent material balances may be written for this system, if mg(kg/h) the total mass balance has been used? 0.60 kg B/kg 2. How many of the unknown flow rates 0.40 kg C/kg and/or mole fractions must be specified before the others may be calculated? 3. Suppose values are given for mand X2. Give a series of equations, each involving only a single unknown, for the remaining variables. Circle the variable for which you would solve
