1. **State the problem:** Solve the equation $$\frac{2x+4}{x-3} = 3$$ for $x$.
2. **Formula and rules:** To solve a rational equation, multiply both sides by the denominator to eliminate the fraction, but remember to check for values that make the denominator zero (excluded values).
3. **Multiply both sides by the denominator:**
$$\cancel{(x-3)} \cdot \frac{2x+4}{\cancel{x-3}} = 3 \cdot (x-3)$$
which simplifies to
$$2x + 4 = 3(x - 3)$$
4. **Expand the right side:**
$$2x + 4 = 3x - 9$$
5. **Bring all terms to one side:**
$$2x + 4 - 3x + 9 = 0$$
which simplifies to
$$-x + 13 = 0$$
6. **Solve for $x$:**
$$-x = -13$$
$$x = 13$$
7. **Check for excluded values:** The denominator $x-3$ cannot be zero, so $x \neq 3$. Since $x=13$ is allowed, it is the solution.
**Final answer:** $$x = 13$$
