Here's the simplified equation:

$$2x - 5 + 2x = 4x - 5$$

To simplify the expression $2x - 5 + 2x$, you combine the like terms.

1. Identify the like terms:

   • $2x$ and $2x$ are like terms (both are terms with $ x $).
   • $-5$ is a constant term.

2. Combine the like terms $2x$ and $2x$:
   $$2x + 2x = 4x$$

3. Combine the result with the constant term:
   $$4x - 5$$

So, the simplified expression is:
$$4x - 5$$
