Answer 2

Let's solve each of the given equations:

1. 82 + (-99) = -17
2. 17 + (-283) = -266
3. -258 + (-552) = -810
4. 645 + (-384) = 261
5. -6.4 + (-6.3) = -12.7
6. 6.9 + (-2.1) = 4.8
7. -4.2 + (-9) = -13.2
8. -35 + 4.7 = -30.3
9. -6.7 + (-79.6) = -86.3

So, the solutions to the given equations are:

1. 82 + (-99) = -17
2. 17 + (-283) = -266
3. -258 + (-552) = -810
4. 645 + (-384) = 261
5. -6.4 + (-6.3) = -12.7
6. 6.9 + (-2.1) = 4.8
7. -4.2 + (-9) = -13.2
8. -35 + 4.7 = -30.3
9. -6.7 + (-79.6) = -86.3
