31<9 and --3X = 4X = 15X = 12X = 11x = 18

Given:
[tex]\frac{3x}{4}<9\text{ and -}\frac{x}{6}\ge-3[/tex]Find: values belong to the solution
Explanation:
[tex]\begin{gathered} \frac{3x}{4}<9 \\ 3x<36 \\ x<12 \end{gathered}[/tex]and
[tex]\begin{gathered} -\frac{x}{6}\ge-3 \\ -x\ge-18 \\ x\leq18 \end{gathered}[/tex]so those values are solution which is x<12
i.e; x=4 and x=11
