USING MATLAB The following system of equations is designed to determine concentrations (x) in a series of coupled reactors as a function of the amount of mass input to each reactor (B) -- which is the right hand side of the system of equation ... A times x = B 15x1 -3x2 - x3 = 3800 -3x1 + 18x2 - 6x3 = 1200 -4x1 - x2 + 12x3 = 2350 a) Determine how much the rate of mass input to reactor 3 must be increased to induce a (30 g/m^3) rise in the concentration of reactor 1? Prove your solution is correct by finding x (using the solution technique of your choice) for both the original case and the modified reactor input -- then subtracting the values. The change for x1 should be 30
