write down 5 pairs of integers whose sum is -15
1st pair --> -10 + (-5) = -15
2nd pair --> -3 + (-12) = -15
3rd pair --> 10 + (-25) = -15
4th pair --> 15 + (-30) = -15
5th pair ---> 1 + (-16) = -15
2nd pair --> -3 + (-12) = -15
3rd pair --> 10 + (-25) = -15
4th pair --> 15 + (-30) = -15
5th pair ---> 1 + (-16) = -15
