To simplify $2x + 5 + x$, combine like terms. The terms $2x$ and $x$ are both in terms of $x$, so you add their coefficients:

$2x + x = 3x$

Thus, the simplified expression is:

$3x + 5$

Final Answer:

$3x + 5$

Tip:

When simplifying expressions, always group similar terms together (e.g., variables with variables, constants with constants) for clarity.
