1. **State the problem:**
We want to find an expression equivalent to $$\frac{1}{\frac{1}{x+2} + \frac{1}{x+3}}$$ for $$x > 3$$.
2. **Recall the formula for sum of fractions:**
$$\frac{1}{a} + \frac{1}{b} = \frac{a+b}{ab}$$
3. **Apply the formula to the denominator:**
$$\frac{1}{x+2} + \frac{1}{x+3} = \frac{(x+2)+(x+3)}{(x+2)(x+3)} = \frac{2x+5}{(x+2)(x+3)}$$
4. **Rewrite the original expression:**
$$\frac{1}{\frac{2x+5}{(x+2)(x+3)}}$$
5. **Simplify by dividing by a fraction:**
$$= 1 \times \frac{(x+2)(x+3)}{2x+5} = \frac{(x+2)(x+3)}{2x+5}$$
6. **Expand the numerator:**
$$ (x+2)(x+3) = x^2 + 3x + 2x + 6 = x^2 + 5x + 6 $$
7. **Final simplified expression:**
$$\frac{x^2 + 5x + 6}{2x + 5}$$
