     The product of the ages of Dora and Phil is 243.  

     Phil is 3 times as old as Dora.

     How old is Phil? 

     DP = 243

     3D^2 = 243

     D^2 = 81 

     D = 9 

     Phil is 27 years old.

    D•P = 243

    P = 3D

    substitute

    D(3D) = 243

    3D² = 243

    D² = 81

    D = √81 = 9

    P = 3D = 27

    check

    27•9 = 243
