Answer 2

Step-by-step explanation:

Case 1 :-

sum is -9

=> integer are => -7and -2

if we add them => -7+(-2) = -9✓✓

Case 2:-

difference is -7

=> integer are -9 and -2

=> if we sub them => -9-(-2) => -9+2 = -7✓✓

case 3

=> sum is zero

=> integer are => -1 and 1

if we add them => -1+1 = 0✓✓
