Answer

To solve the expression \( 779.5 \times 5 - 46.5 \times 19 - 9 \), we will follow these steps:

### Step 1: Calculate \( 779.5 \times 5 \)
\[ 779.5 \times 5 = 3897.5 \]

### Step 2: Calculate \( 46.5 \times 19 \)
\[ 46.5 \times 19 = 883.5 \]

### Step 3: Substitute the results back into the expression
Now we substitute the results from Step 1 and Step 2 into the original expression:
\[ 3897.5 - 883.5 - 9 \]

### Step 4: Perform the subtraction \( 3897.5 - 883.5 \)
\[ 3897.5 - 883.5 = 3014 \]

### Step 5: Subtract 9 from the result
\[ 3014 - 9 = 3005 \]

### Final Answer
The final result of the expression \( 779.5 \times 5 - 46.5 \times 19 - 9 \) is:
\[ \boxed{3005} \]
