hi i need help writing a code that will allow the user to choose which of each of the intersections the user wants to solve for. these are the equations:
1: 100 + 200 = f1 + f3 or f1 + f3 = 300 (1)
2: 300 + f1 = f2 + f4 or −f1 + f2 + f4 = 300 (2)
3: f5 + f2 = 100 +500 or f2 + f5 = 600 (3)
4: f3 + f6 = 100 +300 or f3 + f6 = 400 (4)
5: f4 +f7 = f6 +200 or f4 − f6 + f7 = 200 (5)
6: 200 + 400 = f5 + f7 or f5 +f7 = 600 (6)

As I read it, you need to allow the user to indicate a list of flows (each f1 to f7) and corresponding traffic volumes. Then, list entered, analyze to see whether the user has given enough information to solve the flows exactly; if not, say so and go back to the beginning. If the user gave too much information or gave flow measurements that make the whole system impossible, then say so and go back to the beginning. If the user gave just the right amount of information and it is not contradictory, spit out the list of all of the traffic flows; and then go back to the beginning.

I will give you one more hint on your problem, Victor. The part of the problem statement that says " according to the dimension and rank of the matrix " is an important indication of how you should proceed in writing your requested program. You need to figure out what matrix they are referring to and write your program to proceed accordingly.
