You can put this solution on YOUR website! The three consecutive even integers: x, x+2, x+4
:
This is not hard, just write an equation for what it says:
:
What are three consecutive even integers whose sum is -12 ?
x + (x+2) + (x+4) = -12
combine like terms
3x + 6 = -12
3x = -12 - 6
3x = -18
x =
x = -6
:
The three consecutive integers are:
-6
-6 + 2 = -4
-6 + 4 = -2
:
-2, -4, ,-6 are the 3 integers (they add up to -12, right?)
