Answer:Step-by-step explanation:When we join the columns of two or more matrices having the same number of rows it is known as augmented matrix.Let A= [tex]\left[\begin{array}{ccc}1&6\\0&3\\\end{array}\right][/tex] B= [tex]\left[\begin{array}{ccc}1&0\\0&1\\\end{array}\right][/tex]Then the augmented matrix is(A|B)Note that a vertical line is used to separate te columns of A from the columns of B(A|B) [tex]\left[\begin{array}{ccc}1&6\\0&3\\\end{array}\right | \left\begin{array}{ccc}1&0\\0&1\\\end{array}\right][/tex]This is a simple example of augmented matrix....
