Question 146358: Write an equation which models how old, in years, you will be when you are 3 times as old as the younger person.
Age now (mother) = 35
Younger person (daughter) age now = 14
age difference = 21 years
mother = X + 21
daughter = X
I was thinking it should be 3x + 21 = 3X.
It's not coming out right. Please help.

Mother = M = 35

In x years, the mother will be,

In x years, the daughter will be,

3 1/2 years ago, the mother was 3 times the daughter's age.
The mother was 31 1/2 years old.
The daughter was 10 1/2 years old.
Are you sure the mother and daughter ages are correct??
