Question

Find the inverse

Step by step explanation on how to perform the row operations to find the inverse.

Step 1

First we write using augmented matrix.

Step 2

Make zeros in column 1 except the entry at row 1, column 1 (pivot entry).

Add row 1 to row 2.

Subtract row 1 multiplied by 2 from row 3

Step 3

Make zeros in column 2 except the entry at row 2, column 2 (pivot entry). Divide row 2 by 3
