# How do you tell whether the given value r=8 is a solution to r-3<=9?

Nov 12, 2016

$r = 8$ is a solution.

#### Explanation:

To tell whether the given value is a solution to the inequality, we have to solve the inequality.

$r - 3 \le 9$
$r \le 12$
The given value is $r = 8$. This is a solution to the inequality because 8 is within our domain $r \le 12$.
