Answer

To solve the expression \((-7) + (-9) + 12 + (-16)\), we will follow these steps:

### Step 1: Combine the Negative Numbers
First, we will add the negative numbers together:
\[ (-7) + (-9) = -7 - 9 = -16 \]

### Step 2: Add the Positive Number
Next, we will add the positive number \(12\) to the result from Step 1:
\[ -16 + 12 = -4 \]

### Step 3: Add the Last Negative Number
Finally, we will add the last negative number \((-16)\) to the result from Step 2:
\[ -4 + (-16) = -4 - 16 = -20 \]

### Final Answer
Thus, the final result of the expression \((-7) + (-9) + 12 + (-16)\) is:
\[ \boxed{-20} \]
