A $Left Linear$ grammar is a grammar which has at most one non-terminal on right side and is left recursive.

Now considering the set of strings generated by the given grammar:

$ \{ abbabb,abbaababb,.....\} $

By carefully observing the pattern , we notice that the strings always begin with $ab$ and end with $babb$. Using this information We can easily arrive at the grammar:

$S \rightarrow Ababb$

$A \rightarrow ab|Abaa$
