Answer 2

Answer:

Given:- 3 x 3 square matrix Tip:- Algorithm to find Inverse of a square matrix of ‘n’ order by elementary row transformation (i) Obtain the square matrix, say A (ii) Write A = InA (iii) Perform a sequence of elementary row operation successively on A on the LHS and pre-factor In on the RHS till we obtain the result In = BA (iv) Write A-1 = B Now, We have, A = I3A Where I3 is 3 x 3 elementary matrix Read more on Sarthaks.com - https://www.sarthaks.com/1066535/find-the-inverse-of-the-matrices-by-using-elementary-row-transformations-1-1-2-1-2-3-3-1-1
