1. ') (Strang 2.6.3) Consider forward elimination from A5? = 5 to U if = 6', as applied to the system of equations below: a: + y + z = 5 a: + y + z = 5 :c + y + z = 5 $ + 23; + 32 7 ) y + ZZ = 2 > y + 22: = 2 a: + 3g + 62 11 2y + 5z = 6 z = 2 (3.) Write out the three row operations that have been applied in this process, in the order they are applied. (b) Write out the three row operations that would reverse this process; these are the reverse of the Operations in (3.), applied in reverse order. (0) Write out the augmented matrix form of both the leftmost system, Ar? = E, and the rightmost system, U55 = E. (d) Apply the Operations from (b) to [U 5] and verify that you obtain [A 5] (Q'l'rnnn' 0 R A\\ 'T'lnacn (\"mud-lane are: an nv+nnqinn me nunai-inn 1
