Question: Complete the following statement.
$5 - ( ) = 14$
1. We are given the equation $5 - ( ) = 14$ and need to find the missing number inside the parentheses.
2. Let the missing number be $x$. Then the equation becomes:
$$5 - x = 14$$
3. To solve for $x$, subtract $5$ from both sides:
$$5 - x - 5 = 14 - 5$$
which simplifies to:
$$-x = 9$$
4. Multiply both sides by $-1$ to isolate $x$:
$$\cancel{-1} \times (-x) = \cancel{-1} \times 9$$
which gives:
$$x = -9$$
5. Therefore, the missing number is $-9$.
Final answer: $-9$
