Part 1:
[tex]6b\ \textless \ 24 [/tex]
[tex] \frac{6b}{6} \ \textless \ \frac{24}{6} [/tex]
[tex]b\ \textless \ 4[/tex]
Part 2:
[tex]4b+12\ \textgreater \ 4[/tex]
[tex]4b+12-12\ \textgreater \ 4-12[/tex]
[tex]4b\ \textgreater \ -8[/tex]
[tex] \frac{4b}{4}\ \textgreater \ \frac{-8}{4} [/tex]
[tex]b\ \textgreater \ -2[/tex]
therefore the answer is...
[tex]b\ \textless \ 4[/tex] or [tex]b\ \textgreater \ -2[/tex]
