Question

how to find the inverse of matrix by elementary operations ??​

Answer 1

Answer:

Elementary Raw Operations

• multiply or divide each element in a row by a constant.
• replace a row by adding or subtracting a multiple of another row to it.

Answer 2

Answer:

${\large{\underbrace{\textsf{\textbf{\colour{blue}{⫷}{\color{blue}{\:\:Answer\: :-}}}}}}}$

But we can only do these "Elementary Row Operations":

swap rows.

multiply or divide each element in a a row by a constant.

replace a row by adding or subtracting a multiple of another row to it.
