See the entire simplification process below:

#### Explanation:

First, multiply each of the terms within the parenthesis by $\textcolor{red}{- 3}$:

$2 x \textcolor{red}{- 3} \left(4 x + 7\right) = 2 x - \left(\textcolor{red}{3} \times 4 x\right) - \left(\textcolor{red}{3} \times 7\right) =$

$2 x - 12 x - 21$

Now, combine like terms:

$2 x - 12 x - 21 = \left(2 - 12\right) x - 21 =$

$- 10 x - 21$
