-12,-13,-14

Explanation:

(-12)+(-13)+(-14)=-39
You know you need 3 integers that all have about the same value because they are consecutive, so divide 39 by 3.
39/3=13
You can then use 2 integers, one greater and one less than -13, to reach -39

-12, -13, -14

Explanation:

Given: three consecutive integers with sum of -39

We know that the integers are consecutive, so let
x - 1 = 1"st integer"
x = 2"nd integer"
x + 1 = 3"rd integer"

Since we know that the sum of the three integers is -39, we know that
(x - 1) + (x) + (x + 1) = -39

Solving for this:
(x - 1) + (x) + (x + 1) = -39
x - 1 + x + x + 1 = -39
3x = -39
x = -13

In this case, by substituting the computed x with the values above, we would know that:
1st integer = -14
2nd integer = -13
3rd integer = -12

*Note that it does not matter if you add positive 1 or negative 1 just as long as you use consistent terms and you define your variables properly. So regardless of whether you use x, x - 1, x - 2 to define your three integers or x, x + 1, x + 2, you will still arrive at the same answer.
