\\ \sf\longmapsto  - 3 \leqslant  \frac{6 - 3x}{2}  \leqslant 8 \\  \bf \bull \: using \: cross \: multiplication\\ \sf\longmapsto 2( - 3) \leqslant 6 - 3x \leqslant 8 \\ \\ \sf\longmapsto  - 6 \leqslant 6 - 3x \leqslant 8 \\ \\ \sf\longmapsto  - 6 \leqslant  - 2x \leqslant 8 - 6 \\ \\ \sf\longmapsto  - 6 \leqslant  - 2x \leqslant 2 \\ \\ \sf\longmapsto  - 6 \leqslant x \leqslant  \frac{ 2}{ - 2}  \\ \\ \sf\longmapsto  - 6 \leqslant x \leqslant  - 1

Hence x lies between -6 and -1
