(a) Set up and solve a system of linear equations to find the possible flows in the network shown in the figure. (Use the parameters s and t as necessary.)
(f,, f2, f3, fa, fs, fg, f7) = ( s, 50 +t, s – 100, 100 + s – t, 250 – t, s, t
(b) Is it possible for f, = 130 and f.
= 140? [Answer this question first with reference to your solution in part (a) and then directly from the figure.]
