1. **Stating the problem:** Solve the equation $\frac{x}{4} + 6 = 9 = 12$. This looks like a typo or confusion because there are two equal signs. We will solve the first equation $\frac{x}{4} + 6 = 9$.
2. **Formula and rules:** To solve for $x$, isolate $x$ by undoing addition and division.
3. **Step-by-step solution:**
1. Start with $\frac{x}{4} + 6 = 9$.
2. Subtract 6 from both sides:
$$\frac{x}{4} + 6 - 6 = 9 - 6$$
$$\frac{x}{4} = 3$$
3. Multiply both sides by 4 to cancel the denominator:
$$\cancel{4} \times \frac{x}{\cancel{4}} = 3 \times 4$$
$$x = 12$$
**Final answer:** $x = 12$
