25 + 5 years = 30

5 + 5 years = 10

10 x 3 = 30

x - number of years it will take for Nicole to be exactly three times as old as Aliyah
25 + x  - Nicole's age in x years (future)
5 + x = Aliyah's age x years (future)

Equation:
25 + x = 3 (5 + x)
25 + x = 15 + 3x
3x -x = 25 - 15
2x = 10
2x/2 = 10/2
x = 5

It will take 5 years for Nicole to be exactly three times as old as Aliyah.

Check:
Nicole in five years: 25 + x = 25 + 5 = 30 years old
Aliyah in five years: 5 + x = 5 + 5 = 10 years old

30 years is three times 10 years.
