See a solution process below:

#### Explanation:

First, group like terms:

$2 x + x + 3$

Now, combine like terms:

$2 x + x + 3 \implies$

$2 x + 1 x + 3 \implies$

$\left(2 + 1\right) x + 3 \implies$

$3 x + 3$

If necessary, we could also factor out the common term:

$\left(3 \times x\right) + \left(3 \times 1\right) \implies$

$3 \left(x + 1\right)$

$3 x + 3$

#### Explanation:

Given: $2 x + 3 + x$.

$= 3 x + 3$
We can also factor. Take out the common term, which is $3$.
$= 3 \left(x + 1\right)$
