Question: A= and B-= -1 = = Go T B O W o TN DWW (a) Write down one way to convert A to B using

A= and B-= -1 = = Go T B O W o TN DWW (a) Write down one way to convert A to B using elementary row operations. There are many correct answers to this problem. (b) Can we use elementary row operations to convert B into A7 If so, how do those operations compare to your answer to part (a)? If not, why not? () What is the fewest number of elementary row operations needed to transform A into B? Explain your reasoning
