To simplify the expression \( 2x + 7x - 4x + 8 - x \), we follow these steps:

1. **Combine like terms involving \(x\):**
   \[
   2x + 7x - 4x - x = (2 + 7 - 4 - 1)x = 4x
   \]

2. **Combine the constant terms:**
   \[
   The constant term is \(+8\).
   \]

So, the simplified expression is:
\[
4x + 8
\]
