Math Problem Statement

Solve: -3|x| > -6

Solution

The given inequality to solve is:

3x>6-3 |x| > -6

Step 1: Divide both sides by 3-3 to eliminate the negative coefficient.

Dividing by a negative number reverses the inequality sign:

x<2|x| < 2

Step 2: Interpret the absolute value inequality.

The inequality x<2|x| < 2 means that xx lies between 2-2 and 22. In other words, the solution is:

2<x<2-2 < x < 2

Final Answer:

The correct solution is the interval:

(2,2)(-2, 2)

This matches the first option in the choices provided.
