Simplify the inequality and then check which of those values is included in the solution set:
[tex]\begin{gathered} -3(x-4)>6(x-1) \\ \Rightarrow-3x+12>6x-6 \\ \Rightarrow-3x-6x>-6-12 \\ \Rightarrow-9x>-18 \\ \Rightarrow9x<18 \\ \Rightarrow x<\frac{18}{9} \\ \Rightarrow x<2 \end{gathered}[/tex]From the options -1, 2,7 and 3, the only number which is less tan 2 is -1.
Therefore, the only value below included in the solution set is:
