The given equation is:

\[
8 + 7.5 + x + x = 25
\]

We can simplify the equation step by step.

1. Combine like terms:

\[
15.5 + 2x = 25
\]

2. Subtract 15.5 from both sides:

\[
2x = 25 - 15.5
\]

\[
2x = 9.5
\]

3. Divide both sides by 2:

\[
x = \frac{9.5}{2}
\]

\[
x = 4.75
\]

So, the value of \( x \) is \( 4.75 \).
