Answer:
-12, -11, -10 and -9 add up to -42
Step-by-step explanation:
We can solve this by expressing all four of those integers relative to the first one:
[tex]x + (x + 1) + (x + 2) + (x + 3) = -42\\4x + 6 = -42\\4x = -48\\x = -12[/tex]
so we know that the lowest one is -12, and the other three are sequentially higher value:
-12, -11, -10 and -9
