To solve the equation \( \frac{11}{4}x + 9 = 31 \), we can follow these steps:

  1. Subtract 9 from both sides: \[ \frac{11}{4}x = 31 - 9 \] \[ \frac{11}{4}x = 22 \]

  2. Multiply both sides by \( \frac{4}{11} \) to isolate \( x \): \[ x = 22 \times \frac{4}{11} \]

  3. Simplify: \[ x = \frac{88}{11} = 8 \]

So the solution is: \[ x = 8 \]

Thus, the correct response is x = 8.
