Simplify the following  3x−1212x÷x2−1616x÷x+9x+4

To simplify the given expression:

\[
\frac{3x - 12}{12x \div x^2 - \frac{16x}{x}} + 9x + 4
\]

### Step 1: Simplify each term

- **First term: \( \frac{3x - 12}{12x \div x^2 - \frac{16x}{x}} \)**

#### Numerator:
The numerator is \( 3x - 12 \). We can factor this:

\[
3x - 12 = 3(x - 4)
\]

#### Denominator:
The denominator has two parts:

1. \( 12x \div x^2 = \frac{12x}{x^2} = \frac{12}{x} \)
2. \( \frac{16x}{x} = 16 \)

So the denominator becomes:

\[
\frac{12}{x} - 16
\]

### Step 2: Rewrite the expression

The simplified expression now looks like this:

\[
\frac{3(x - 4)}{\frac{12}{x} - 16} + 9x + 4
\]

We now need to simplify the fraction on the left-hand side before proceeding further.
