What is the sum of 3 consecutive odd integers is -39

The three consecutive odd integers are:  -15, -13, and -11 .

Explanation:

  x + (x + 2) + (x + 4) = -39 ;

 in which "x" is one of the integers, 
           "(x + 2)" is the next consecutive odd integer;
           "(x + 4)"  is the third consecutive odd integer.

By solving for "x", we can solve for each of three (3) consecutive odd integers.

     x + (x + 2) + (x + 4) = -39  ;

          1x + 1x + 2 + 1x+ 4 = -39 ;
 
                   3x + 6 = -39 ;

               Subtract  "6" from EACH side of the equation:

                    3x + 6 − 6  =  -39 − 6 ;

        to get:   3x = -45 ;

           Divide EACH side of the equation by "3" ;

                 3x / 3 = -45 / 3 ;

        to get:   x = -15 ;

     x + 2 =  -15 + 2 = -13 ;

     x + 4 =  -15 + 4 =  -11 .

Are: -15, -13, and -11 ;  Consecutive odd integers?  YES!

Does:  -15 + (-13) + (-11)  =? = -39 ??

           -15 − 13 − 11 = ? 39 ??  YES!

The three consecutive odd integers are:  -15, -13, and -11.
