.
<pre>

The numbers are x and (x+1).


Write equation as you read the problem


    (x+1) - 2x = 55.


Simplify and solve


    x + 1 - 2x = 55

    -x         = 55-1

    -x         = 54

     x         = -54


<U>ANSWER</U>.  The numbers are  -54  and -53.


<U>CHECK</U>.  -53 - 2*(-54) = -53 + 108 = 55    exactly as stated in the problem.    ! Correct !
