Solution Steps

Step 1: Rewrite the Equation

We start with the equation: \[ \frac{4}{x-3} + \frac{3}{x+8} = \frac{9}{(x+8)(x-3)} \]

Step 2: Find a Common Denominator

The common denominator for the left-hand side is \((x-3)(x+8)\). We rewrite the left-hand side: \[ \frac{4(x+8) + 3(x-3)}{(x-3)(x+8)} = \frac{9}{(x+8)(x-3)} \]

Step 3: Simplify the Numerator

Now, we simplify the numerator: \[ 4(x+8) + 3(x-3) = 4x + 32 + 3x - 9 = 7x + 23 \] Thus, the equation becomes: \[ \frac{7x + 23}{(x-3)(x+8)} = \frac{9}{(x+8)(x-3)} \]

Step 4: Cross-Multiply

Cross-multiplying gives us: \[ 7x + 23 = 9 \]

Step 5: Solve for \( x \)

Now, we solve for \( x \): \[ 7x = 9 - 23 \] \[ 7x = -14 \] \[ x = -2 \]

Step 6: Determine the Type of Equation

Since we found a single solution \( x = -2 \), the equation is classified as a conditional equation.

Conclusion

The solution set is: \[ \{-2\} \] And the equation is a conditional equation.

Final Answer

The correct answer is A. The solution set is \( \boxed{\{-2\}} \). The equation is a conditional equation.
