Question

( x= )
( A^{infty}=left[begin{array}{ll}1 & -2 -2 & 1end{array}right] )
( A^{-}=left[begin{array}{ll}1 & 2 2 & 1end{array}right] )
( x=1^{-} ) B
( x=left[begin{array}{ll}1 & 2 2 & 1end{array}right]left[begin{array}{c}-3 -1end{array}right] )
( x=left[begin{array}{l}-5 2end{array}right] )

# 1 -27 Find matrix X such that AX = B, where A= and B=L 1-21)
