I need this problem solved in Matlab showing the code and it needs to be done using gauss elimination without pivoting

QUESTION 2: (Problem 9.12) A peristaltic pump delivers the flow (1) of a highly viscous fluid. The network is depicted in Fig. P9.14. Every pipe section has the same length and diameter. The mass and mechanical energy balance can be simplified to obtain the flows in every pipe. Solve the following system of equations to obtain the flow in every stream. (Take Q7-5). Use Gauss elimination without pivoting (fig. 9.4) 0i 0s FIGURE P9.14 30-20 0
