PROBLEM 4E

Row reduce the matrices to reduced echelon form. Circle the pivot positions in the final matrix and in the original matrix, and list the pivot columns.

ANSWER:

Answer:

Step 1 :

In this problem we need to reduce the matrices to reduced echelon form and we have to circle the pivot positions in the final matrix and in the original matrix , and list the pivot columns.

Given matrices is :

Make zeros in column-1 except entry at row -1 and row-3 , column 1,3(pivot entries).

Subtract row -1 multiplied by 3 from row -2 $({R}_{2}\ ={R}_{2}\ \ -3{R}_{1})$

Subtract row-1 multiplied by 5 from row-3 $({R}_{3}\ ={R}_{3}\ \ -5{R}_{1})$
