Answer 1

To evaluate the expression given \( m = 2 \) and \( n = 2 \), we first compute the two parts of the expression:

1. Numerator: \( m + n - 12 \) \[ m + n - 12 = 2 + 2 - 12 = 4 - 12 = -8 \]

2. Denominator: \( mn - m \) \[ mn - m = (2)(2) - 2 = 4 - 2 = 2 \]

Now, we can substitute these values into the overall expression: \[ \frac{m + n - 12}{mn - m} = \frac{-8}{2} = -4 \]

Thus, the final simplified answer is: \[ \boxed{-4} \]
