Answer:
The required answer is [tex]{x|x < -2}[/tex].
Step-by-step explanation:
Consider the provided inequality
[tex]3x<-6[/tex]
Divide both side by 3.
[tex]3x<-6[/tex]
[tex]x<\frac{-6}{3}[/tex]
[tex]x<-2[/tex]
The sign of inequality will remain same.
Therefore, the required answer for the provided inequality is [tex]{x|x < -2}[/tex].
