.

Tina  x hours

Louise 2x hours



Then you write an equation as you read the text

    x + 2x = 108  hours



Next you simplify and solve

      3x   = 108

       x   = 108/3 = 36.



ANSWER.  Tina worked 36 hours.   Louise worked  2*36 = 72 hours.


CHECK.   36 + 72 = 108  hours,  total combined time.    ! Correct !

Solved, and carefully explained.
