Explanation of Solution

Using Gauss-Jordan method to indicate the solutions:

Consider the given system of linear equations,

x1x3=4x2+x3=2x1+x2=5

The augmented matrix of this system is as follows:

A|b=[1 0 -10 1 11 1 0][425]

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

Replace row 3 of A|b by (row 3 – row 1), then the following matrix is obtained,

A1|b1=[1 0 -10
