Intergers***

directrix · Answer

Intergers***  should be Integers. There is only one "r" in Integer.

Let x represent the first of the three consecutive odd integers.
x + 2 is the second
and
x + 4 is the third.

Solve this equation for x:

x + x + 2 + x + 4 = -15

What number would be x ?

directrix · Answer

To know that, you need to solve this equation:  x + x + 2 + x + 4 = -15

 x + x + 2 + x + 4 = -15
3x + 6 = -15
For the next step, subtract 6 from both sides.
