Answer 1

Answer:

fd

Step-by-step explanation:

Given matrix is,

We have to find    using elementary row operation.

So first we have to combine this matrix with identity matrix to form an augmented matrix like,

Now let's begin!

Now we get another augmented matrix consists of identity matrix at left. So,
