^someone verify me on that i'm not very intelligent

 

It the beginning, Rosa is twice as old as Pilar, meaning she's older than Pilar. In 4 years however, Rosa's age would be 2 years less than Pilars age 3 years ago, implying that Rosa is younger than Pilar. That doesn't make sense, referring to the beginning of the problem. Therefore, I found that there was no solution.

Hello Guest!

 

\(r+10=2p\\ r+4=(p-3)-2\\ 2p+4=p-5\\ 3p=-9 \)

\(p=-3\)

\(r=2p\)

\(r=-6\)

 

Rosa and Pilar are planned children.
Pilar will be born in three years, Rosa in 6 years.

This is nonsense.
The task has a logical error.
