You can put this solution on YOUR website! rita's age is 3 times anna's. when anna is twice as old as she is now, rita's age will only be twice anna's. how old is each now?
Let A = Anna's age
3A = Rita's age
2A = age of Ana A years from now
3A + A = Rita's age when Ana's age is twice as old as she is now
= 2(2A)
4A = 4A
A can be any positive number.
Meaning:
When Ana is 1 year old, Rita is 3 years old.
When Ana is 5 years old, Rita is 15 years old.
When Ana is 10 years old, Rita is 30 years old.
...and so on.
