When Kirchoff's laws are explained to an electrical circuit, the set of simultaneous equations below are obtained. (I will attach a picture in the comment). What I need is from the method I have used clearly explain the method/technique used and to validate the solution/ method by using an alternative mathematical method. #Special thanks to @Michele_Laino and @UsukiDoll for the help on my previous question.

    ya, u are doing it right, just sub the currents back into the system of equations to see if it is working out

    I only know the matrix and the Reduce Row Echelon (Gaussian Elimination) . As Dan mentioned, substitute the values you got from using row operations and see if x, y, and z work out for each equation that was given.

    At the bottom i have put them back into the equation twice and the both work out fine but with a very small error.

    So for what i have put as my answer would someone be able to highlight the method and techniques used.i.e. break down into small groups

    you know how yo said what you was doing with the last question in stages would you be able to do that for what i have already done. e.g. sub 2 into and it gives us.

    thank you. i will pop to lunch as if not i will miss t today. And to think these are the easy questions. I'm dreading next lesson as i will be getting the last assignment back for further maths and I think i did terrible.

    tip: keep your answers for x y and z in fraction form. decimals are a pain.

    Though I have to confess.. RREF (reduced row echelon form) would've been better.
