(b) Calculate the unknown currents I1, I2, I3, I4 and I5 for the circuit shown below using a matrix technique. Hint: Setup the equations for the unknowns using Kirchhoff's current and voltage laws and put into a matrix form and solve the matrix to find the unknown currents. Use the calculator (TI 84+ etc) or python code or matlab or manual methods. Search youtube on how to solve the matrix using your calculator
