Help!!!! im really not sure, please help.

Answer:
Ruben is 9, Mike is 3.
Step-by-step explanation:
In 3 years, Ruben will be twelve, which is twice as old as 6, the age of Mike in 3 years. Also, 9 (the age of Ruben right now) minus 6 is 3 (the age of mike right now).
Answer:
Ruben would be 9 and Mike would be 3
Step-by-step explanation:
If you multiply 6 times 2 it is twelve which will be the only age when Ruben is twice the age of Mike. So when you find how old they will be in 3 years (12 and 6), you can then subtract both numbers by three and find how old they are right now (9 and 3).
