It takes Myline twice as long as Jeana to do a certain piece of work. Working together, they can finish the work in 6 hours. How long would it take Jeana to do it alone?

Their combined rate is 1 job per 6 hours or  or 

Jeana's rate is 1 job per x hours or  or 

Myline's rate is 1 job per 2x hours or  or 

The equation comes from  +  = 

                                      +  = 

Multiply through by LCD = 6x and solve.  You'll get 9 hours.
