We combine like terms in order to simplify expression. To do so, we combine terms with the same variable and exponents. In this exercise, let's apply distributive property first:

Answer:
.
Step-by-step explanation:
It is given that three times a number r plus 8 is fewer than −12.
We need to write the sentence as an inequality.
Three times a number r = 3r
Times a number r plus 8 = 3r+8
Fewer than = less than = <
So, the inequality for the sentence "three times a number r plus 8 is fewer than −12" is

Therefore, the required inequality is
