1. The problem is to solve the inequality $4|x-3| > 12$.
2. We start by isolating the absolute value expression. Divide both sides by 4:
$$\frac{4|x-3|}{\cancel{4}} > \frac{12}{\cancel{4}}$$
which simplifies to
$$|x-3| > 3$$
3. Recall the rule for absolute value inequalities: For $|A| > B$ where $B > 0$, the solution is $A < -B$ or $A > B$.
4. Applying this rule to $|x-3| > 3$, we get two inequalities:
$$x-3 < -3 \quad \text{or} \quad x-3 > 3$$
5. Solve each inequality separately:
- For $x-3 < -3$:
$$x < 0$$
- For $x-3 > 3$:
$$x > 6$$
6. Therefore, the solution set is:
$$x < 0 \quad \text{or} \quad x > 6$$
This means any $x$ less than 0 or greater than 6 satisfies the original inequality.
