SOLUTION:
- The word problem can be written in algebraic equation as [tex]\rm 3x+11=35[/tex]. Thrice means to multiply a particular number by three and the term “increased by” symbolizes the operation of addition.
Let’s now solve for the value of the unknown number, x.
[tex]\large{\rm 3x+11=35}[/tex]
[tex]\large\rm3x=35-11[/tex]
[tex]\large\rm3x=24[/tex]
[tex]\large\rm x=24/3[/tex]
[tex]\boxed{\large\rm x=8}[/tex]
Therefore, the value of x is 8.

ANSWER:
- The number is 8, hence, the correct answer is the third option.
