In 2000 Emily was 9 years old.

Given that in the year 2015 Emily was three times as old as Kaitlin while by the year 2021 Kaitlin will be half as old as Emily will be, to determine how old was Emily on the year 2000 the following calculation must be performed:

  • 2015 = E = 3K
  • 2021 = E = 2K  
  • 24 /// 8 --- 30 /// 14
  • 18 /// 6 --- 24 /// 12
  • 18/6 = 3
  • 24/12 = 2
  • 2015 = Emily was 24 years old
  • 24 - (2015 - 2000) = X
  • 24 - 15 = X
  • 9 = X

Therefore, in 2000 Emily was 9 years old.

Answer:

21

Step-by-step explanation:

If x was more than 1, then it would be impossible because fx would have to be even, but 4x+3 would be odd. Therefore, x must equal 1, and f must equal 7. This means that 3f=21
