Answer:

<u>The numbers are -61 and -68</u>

Step-by-step explanation:

x = Smaller number

y = Larger number

x + y = - 129

y = x + 7

*********************************

x = - 129 - y

*********************************

Substituting x and solving for x and y, we have:

y = -129 - y + 7

2y = - 129 + 7

2y = -122

y = -122/2

y = -61 ⇒ x = -68

<u>The numbers are -61 and -68</u>
