# How do you solve the inequality abs(9-4x)<=0?

Jun 21, 2017

This is a special case.

#### Explanation:

Since any absolute value, such as the one in our problem, is always greater than or equal to zero, the only solutions to
$| 9 - 4 x | \le 0$ occur when $9 - 4 x = 0$. Simply solve this linear equation for x, and you will have the solution.
