So with this, all you need to do is multiply both sides by -3. And remember because you are multiplying with a negative, the sign will flip as well. After doing this step, your answer will be x > -18, or B.

When we multiply or divide both sides of an inequality by a negative number, the sense of the the inequality flips:


[tex] \dfrac{x}{-3} < 6 [/tex]


[tex] \dfrac{x}{-3} \cdot -3 > 6 \cdot -3 [/tex]


[tex] x > - 18 [/tex]
