ANSWER
See attachment.
EXPLANATION
The given inequality is
[tex]3x \: < \: 8[/tex]
Divide both sides by 3 to get,
[tex]x \: < \: \frac{8}{3} [/tex]
[tex]x \: < \: 2 \frac{2}{3} [/tex]
Because the inequality involves '<' we use a hollow circle at 2⅔.
The solution set of this inequality is shown on the number line in the attachment.
