1. **State the problem:** Simplify the expression $(x-9)-(4-2x)$.
2. **Apply the distributive property:** Remove the parentheses by distributing the minus sign to the second group:
$$ (x-9) - (4-2x) = x - 9 - 4 + 2x $$
3. **Combine like terms:** Group the $x$ terms and the constants:
$$ x + 2x - 9 - 4 $$
4. **Simplify:**
$$ 3x - 13 $$
**Final answer:**
$$3x - 13$$
