2х + П/4 + 4х/2

To simplify the expression \( 2x + \frac{\pi}{4} + \frac{4x}{2} \), we can first simplify the term \( \frac{4x}{2} \):

\[ \frac{4x}{2} = 2x \]

Now, we can rewrite the entire expression:

\[ 2x + \frac{\pi}{4} + 2x \]

Next, combine the \( 2x \) terms:

\[ 2x + 2x = 4x \]

So, the expression simplifies to:

\[ 4x + \frac{\pi}{4} \]

Therefore, the final simplified expression is:

\[ 4x + \frac{\pi}{4} \]
