Q1)
[-1 4 1]
determine A-1 as an intermediate step.
(Hint: Suppose after row reduction RX = C and R = |r2|and X = [x1 : x2 : x3]. Express the elements of matrix C in
terms of r, xj. Note that RX = C may be solved by using R[x1 : x2 : x3]
C and solving three linear systems.)](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F7239ecac-0f98-405d-b013-f46f97e551ad%2F129b88de-5e96-4005-9e7e-7169fe8a51c7%2Fvx7jx3_processed.png&w=3840&q=75)
