A process involving mass balances is described by the following equations: m = m + m3 + m4 +m5 m = mg + m10 + m1 m5 = mg + m7+m6 m12 = m4 +m7 + m1 m1 100 m5 = 5mg 0.84 m 12 m +m7 0.7 m = m2 + m3 0.55 m = mg + m12 0.2 mg m10 0.85 m2 mg + m11 = = 3.6 me m7 +m8 m6 = write a Matlab script that: (a) generates the matrix A and vector b required to solve the system of equations, and (b) solve the system using Gauss elimination.
