Answer:
-12, -11, -10 and -9 add up to -42
Explanation:
We can solve this by expressing all four of those integers relative to the first one:
![x + (x + 1) + (x + 2) + (x + 3) = -42\\4x + 6 = -42\\4x = -48\\x = -12](https://img.qammunity.org/2021/formulas/mathematics/high-school/dmo3leb87ktldx1zyc3bp1c4kaeutb8cxy.png)
so we know that the lowest one is -12, and the other three are sequentially higher value:
-12, -11, -10 and -9
