1. Find a \& b so that A=4106a45b6hasaninverseofA1=03/81/413/211/27/161/8 2. Solve AX+B=C for A above, B=23453101,C=[421102][16] Do NOT use a Gaussian Elimination. Let B=E3E2E1A. A has had several row operations applied to result in B. Using notations: RiRj,RiRi,cRiRjRj, Describe in correct order, how A became B. E1=100010003E2=140010001E3100001010
