I doubt it says "or". It's probably an and.
[tex]\dfrac{-2}{3}x > 8\wedge\dfrac{-2}{3x} < 4[/tex]
[tex]-2x > 24\wedge3x < \dfrac{4}{-2}[/tex]
[tex]x > -12\wedge x < -\dfrac{2}{3}[/tex]
[tex]\Rightarrow\boxed{-12 < x < -\dfrac{2}{3}}[/tex]
[tex]\Rightarrow\boxed{x\in(-12,-\dfrac{2}{3})}
[/tex]
Hope this helps.
