The given equation is:

\[
\frac{\sqrt{9x + 27}}{2x + 10} + \frac{\sqrt{9x + 27}}{x + 5} = 1
\]

To solve this equation, let’s follow these steps:

### Step 1: Simplify the Square Root
Notice that:
\[
9x + 27 = 9(x + 3)
\]
So,
\[
\sqrt{9x + 27} = \sqrt{9(x + 3)} = 3\sqrt{x + 3}
\]

Substitute \(3\sqrt{x + 3}\) for \(\sqrt{9x + 27}\) in the equation:

\[
\frac{3\sqrt{x + 3}}{2x + 10} + \frac{3\sqrt{x + 3}}{x + 5} = 1
\]

### Step 2: Factor and Simplify the Denominators
Observe that \(2x + 10 = 2(x + 5)\), so rewrite the equation as:

\[
\frac{3\sqrt{x + 3}}{2(x + 5)} + \frac{3\sqrt{x + 3}}{x + 5} = 1
\]

### Step 3: Combine Terms
Since both terms have \(\sqrt{x + 3}\) in the numerator and a common denominator of \(x + 5\), factor out \(\frac{3\sqrt{x + 3}}{x + 5}\):

\[
\frac{3\sqrt{x + 3}}{x + 5} \left(\frac{1}{2} + 1\right) = 1
\]

Simplify inside the parentheses:

\[
\frac{3\sqrt{x + 3}}{x + 5} \cdot \frac{3}{2} = 1
\]

### Step 4: Solve for \(\sqrt{x + 3}\)
Multiply both sides by \(\frac{2}{3}\) to isolate \(\frac{3\sqrt{x + 3}}{x + 5}\):

\[
\frac{3\sqrt{x + 3}}{x + 5} = \frac{2}{3}
\]

Now multiply both sides by \(x + 5\):

\[
3\sqrt{x + 3} = \frac{2}{3}(x + 5)
\]

### Step 5: Square Both Sides to Eliminate the Square Root
\[
9(x + 3) = \left(\frac{2}{3}(x + 5)\right)^2
\]

Expanding and simplifying from here will help us find the values of \(x\). Would you like to proceed with the expansion, or have additional steps clarified?
