a) Deduce the set of linear equations from this flow problem.
b) Apply the Gaussian Elimination technique to transform the system into a Row-
Echelon form and determine all the possible flows along each street.
c) Are all the solutions acceptable in real situations? If not, state the constraint(s)
that might be imposed to ensure that all the solutions are realistic.
