First we represent the unknowns:

Let x = daughter's present age

Let 2x = mother's present age

According to the problem, 20 years ago, the mother was three times older than her daughter. Thus,

2x - 20 = 3(x - 20)

Solving for x,

2x - 20 = 3x - 60

2x - 3x = -60 + 20

-x = -40

x = 40 years old (daughter, present age)

2x = 80 years old (mother, present age)

hope this helps~ :)
