Let's solve the equation step by step:

\[
\frac{1}{2}x + 10 = \frac{10}{x - 25} - \frac{2}{x - 5}
\]

### Step 1: Find a common denominator on the right-hand side.
The common denominator for \( x - 25 \) and \( x - 5 \) is \( (x - 25)(x - 5) \). Let's rewrite both terms with this common denominator:

\[
\frac{10}{x - 25} = \frac{10(x - 5)}{(x - 25)(x - 5)}
\]
\[
\frac{2}{x - 5} = \frac{2(x - 25)}{(x - 25)(x - 5)}
\]

Now substitute these into the equation:

\[
\frac{1}{2}x + 10 = \frac{10(x - 5) - 2(x - 25)}{(x - 25)(x - 5)}
\]

### Step 2: Simplify the numerator on the right-hand side.
Expand both terms in the numerator:

\[
10(x - 5) = 10x - 50
\]
\[
-2(x - 25) = -2x + 50
\]

So, the right-hand side becomes:

\[
\frac{1}{2}x + 10 = \frac{(10x - 50) - (2x - 50)}{(x - 25)(x - 5)} = \frac{10x - 50 - 2x + 50}{(x - 25)(x - 5)}
\]

Simplifying the numerator:

\[
10x - 2x - 50 + 50 = 8x
\]

Now the equation is:

\[
\frac{1}{2}x + 10 = \frac{8x}{(x - 25)(x - 5)}
\]

### Step 3: Multiply both sides by \( (x - 25)(x - 5) \).
This eliminates the denominator on the right-hand side:

\[
\left(\frac{1}{2}x + 10\right)(x - 25)(x - 5) = 8x
\]

Expanding the left-hand side:
First, distribute \( \frac{1}{2}x + 10 \) to \( (x - 25)(x - 5) \), but this will be quite complex, so for clarity, I'll leave it in this form for now.
