Answer 2

Let's break down the given expression step by step:

1. Calculate $4 \frac{2}{7} + 4$: $4 \frac{2}{7} + 4 = 4 + \frac{2}{7} \times 7 + 4 = 4 + 2 = 6$

2. Calculate $25 - 2$: $25 - 2 = 23$

3. Calculate $19 - 4 \frac{2}{7}$: $19 - 4 \frac{2}{7} = 19 - \left(4 + \frac{2}{7} \times 7\right) = 19 - 4 - 2 = 13$

Now, substitute the calculated values into the original expression:

$-(4 \frac{2}{7} + 4) + (25 - 2) - (19 - 4 \frac{2}{7})$

$= -(6) + (23) - (13)$

Now, perform the operations in the correct order:

$= -6 + 23 - 13$

$= 4$
