Answer: FIRST OPTION.
Step-by-step explanation:
To know which is the solution set given the inequality [tex]3x < -6[/tex] you need to solve for the variable "x".
You must divide both sides by 3:
[tex]3x < -6\\\\\frac{3x}{3}=\frac{-6}{3}[/tex]
Therefore, you get:
[tex]x<-2[/tex]
Then, the solution set is the following:
{[tex]x | x < -2[/tex]}
You can observe that this solution set matches with the first option.
