Simplify the expression shown.

3x + 2 – 3x + 7 +5x

What is the coefficient in the simplified expression? 

5
9
3x
5x

To simplify the expression \( 3x + 2 - 3x + 7 + 5x \):

1. Combine the \( x \)-terms: 
   \[
   3x - 3x + 5x = 5x
   \]

2. Combine the constant terms:
   \[
   2 + 7 = 9
   \]

So the simplified expression is:
\[
5x + 9
\]

The coefficient of \( x \) in the simplified expression is **5**.
