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