First you had to multiply by ten from both sides of equation form.
[tex]2.9(x+8)*10<26.1*10[/tex]
Then refine by simplify.
[tex]29(x+8)<261[/tex]
Next, you divide by twenty-nine from both sides of equation form.
[tex]\frac{29(x+8)}{29}< \frac{261}{29}[/tex]
Simplify.
[tex]x+8<9[/tex]
Then you subtract by eight from both sides of equation form.
[tex]x+8-8<9-8[/tex]
Finally, simplify by equation.
[tex]9-8=1[/tex]
[tex]x<1[/tex]
Final answer: [tex]\boxed{x<1}[/tex]
Hope this helps!
And thank you for posting your question at here on brainly, and have a great day.
