Solve by using reduced Echelon form A network of irrigation ditches is shown in Figure, with flows measured

A network of irrigation ditches is shown in Figure, with flows measured in thousands of liters day. a) Set up and solve a system of linear equations to find the possible flows. b) Suppose DC is closed. What range of flow will need to be maintained through DB? c) From Figure it is clear that DB cannot be closed. (why not?) How does your solution in part(a) show this? d) From your solution in part(a), determine the minimum and maximum flows through DB. 150 C 150 100 A B 1 200 D 25C Mostly cloudy per
