Indicating the solutions using Gauss-Jordan method:

Consider the following system of equations.

2x1−x2+x3+x4=6 x1+x2+x3=4

The augmented matrix of this system is given below:

A|b=(2−111611104)

The Gauss-Jordan method is applied to find the solution to the above system of equations.

Replacing row 2 by row 1 of A|b, we get

A1|b1=(111042−1116)

Now, replace row 2 of A1|b1 by (row 2 of A1|b1) – 2(row 1 of
