To determine the coefficient of \( x \) in the expression \( 4x - 2(x + 3) \), we begin by simplifying the expression.

First, distribute the \(-2\) to both \( x \) and \( 3 \) inside the parentheses:

\[

-2(x + 3) = -2x - 6

\]

Now, substitute this back into the original expression:

\[

4x - 2(x + 3) = 4x - 2x - 6

\]

Next, we combine the like terms related to \( x \):

\[

4x - 2x = 2x

\]

After combining, we can rewrite the expression as:

\[

2x - 6

\]

From this expression, it is clear that the coefficient of \( x \) is \( 2 \). Therefore, the correct answer identifies that the coefficient in front of \( x \) is \( 2 \).
