Let's denote the unknown number as \( x \).
According to the problem, the equation can be set up as follows:
\[ \frac{8 + x}{3} = 6 \]
Now, let's solve for \( x \).
- Multiply both sides of the equation by 3 to eliminate the fraction:
\[ 8 + x = 18 \]
- Subtract 8 from both sides:
\[ x = 18 - 8 \]
- Simplify:
\[ x = 10 \]
However, 10 is not one of the answer choices provided (6, -2/3, -6, 52). Therefore, let me double-check:
The equation format is correct, and the calculations show that \( x \) should be 10. None of the answer choices listed match the value calculated.
Is there a possibility of an error with the choices given? If you have more details or further context, please let me know!
