Answer:
The numbers are -61 and -68
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
The numbers are -61 and -68
