Question

Let A be the matrix below and define a transformation T:R³  ---> R³  by T(u) = Au. For each of the vectors b below, find a vector u such that I maps u to b, if possible. Otherwise state that there is no such u

1    2    2
A= -2  -4    1
     -2  -3   -2

(a) b= 11
           -2
          -12

(b) b=  1
           -2
           -1
