question is in the picture 9 What is the solution set of 7? -7 -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6 7 X -7 -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6 7 X O +HH. -7 -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6 7 x -7 -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6 7 X

both-6x < 21
divide both sides by -6
[tex]\begin{gathered} \frac{-6x}{-6}\text{ > }\frac{21}{-6} \\ \\ x\text{ > -3.5} \end{gathered}[/tex]The correct option is option D
