Let's assume Nicole's age is x now.
So, Kristin's age is (32 - x).
After 2 years, Nicole's age will be x + 2, and Kristin's age will be (32 - x) + 2.
According to the problem, Nicole's age will be three times Kristin's age after 2 years.
So, the equation will be written as:
x + 2 = 3((32 - x) + 2)
x + 2 = 3*(34 - x)
x + 2 = 102 - 3x
4x = 100
x = 25
So, Nicole's age is 25, and Kristin's age is 32 - 25 = 7
