Circuits on Excel

So the Hw is due tomorrow and I need it as early as possible. The Hw is about circuits and voltages currents and related laws. The hw also have to be done and solved at the excel sheet or spreadsheet that shows the diagram of the circuit and the calculations specifics in the questions. Also I think there should be a Matrix done with it after finding the KVL' and KCL's in the excel sheet. The mmult and minverse functions. There are the problems that need to be done. each sepreatley on a different tab of excel sheet.
