 
Carolina, I would let Mandy's age be M years and Randy's age be R years. I am going to show you how to set up two equations in M and R that you can solve. The first statement
tells you that
How old will Randy be in 12 years? At that time Mandy's age is half of Randy's. That's the second equation. Solve for M and R. Don't forget to check your answer.
