Question 1148026: Using Gauss Jordan method solve equations 83x+11y-4z=95;7x+52y+13z=104;3x+8y+29z=71 Found 2 solutions by greenestamps, ikleyn:Answer by greenestamps(13203) (Show Source):
An online program for solving systems of equations shows the solutions are very ugly fractions; specifically, z is a fraction with numerator and denominator each 6 digits. It will be a waste of time for either me or you to try to solve the system using Gauss-Jordan.
The Gauss-Jordan process is straightforward, but there are always endless variations on the sequence of steps used to find a solution.
Find a simpler system of equations for getting practice using the process.
