1. **State the problem:** Solve the equation $\frac{2x+4}{3} = 5$ for $x$.
2. **Formula and rules:** To solve equations involving fractions, multiply both sides by the denominator to eliminate the fraction.
3. **Multiply both sides by 3:**
$$\cancel{3} \times \frac{2x+4}{\cancel{3}} = 5 \times 3$$
which simplifies to
$$2x + 4 = 15$$
4. **Isolate $x$:** Subtract 4 from both sides:
$$2x + 4 - 4 = 15 - 4$$
$$2x = 11$$
5. **Divide both sides by 2:**
$$\frac{\cancel{2}x}{\cancel{2}} = \frac{11}{2}$$
which gives
$$x = \frac{11}{2}$$
6. **Final answer:**
$$x = \frac{11}{2}$$
