Problem 2 Use MATLAB to construct the augmented matrix [A b] and then perform row reduction using the rref() function. Write out your reduced matrix and identify the free and basic variables of the system. Solution: A = [2 1 0 0 0; 1 1 -1 0 -1; -1 0 1 0 1; 0 -1 0 1 1; 0 1 1 -1 1] b = [100; 0; 50; 120; 0] AugA = [A eye (5)] [rowreducedAugA, pivotvarsAugA] = rref (AugA)|

Hello! I need help with the following MATLAB code. This is what I have so far but I feel like I am missing something, and that it is not entirely correct. 

Thanks in advance!

Scenario You are employed as a network engineer and have been asked to analyze a communication network to determine the current data rates and ensure that the links aren't at risk of "reaching capacity." In the following figure of the network, the sender is transmitting data at a total rate of 100+50 = 150 megabits per second (Mbps). The data is transmitted from the sender to the receiver over a network of five different routers. These routers are labeled A, B, C, D, and E. The connections and data rates between the routers are labeled as X1, X2, x3, x4, and x5. Sender 100 50 A ((4₁³)) X2 C c (()). X3 X2 X₁ E ((4)), X5 X5 X4 B D (cp)) (cp) X3 120 Receiver
