MATH1131 Linear Algebra: Chapter 4 Problem 14 h

Here we solve the system of linear equations which is a set of 3 equations in 4 unknowns by using Gaussian elimination to transform the corresponding augmented matrix of the system of equations into row-echelon form. Presented by N J Wildberger of the School of Mathematics and Statistics, Faculty of Science, UNSW.

do we have to make it into fully reduced row-echelon form to solve? Can we just solve from the reduced form?

Even though your leading entry is not equal to 1 you still get same answer. No one will doing that like you

[肖富安]

you don't really to simplify that much it make student confused. you still can get the same answer in the end. Make sure don't do that next time.
