Hi

Three years ago I was six times as old as you

Let x and 6x represent Amanda's and her grandmother's ages '3 years ago'

Question states*** 6 years after that time...

 6x + 6 = 4(x + 6)

solving for x

 6x + 6 = 4x + 24

    2x = 18

     x = 9, Amanda's age 3 year ago. Her grandmother was then 54.

NOW, the grandmother is 57



CHECKING our Answer*** (Amanda is NOW 12)

57 + 3 = 4(12 + 3) = 60
