Explanation of Solution

Solving the given linear system:

Consider the given system of linear equations,

x1+x3=44x1+x22x3=03x1+x2x3=2

For a system of the form Ax=b, it can be written as follows:

x=A-1b

For the given system of linear equations, the inverse obtained in Problem 2 can be used, which is given below,

A-1=[12 12 -12-1 -2 312 -12 12]

Thus, it can be written as follows:

A-1
