(G-12)=M
(G+1)/2=M

(G-12)=(G+1)/2
2G-24=G+1
G=25

25-12=13

Gabriela is 25, Maria is 13. Last anno they were 24 and 12.

This is it dato te mean "She was twice the age of Maria" when te say "She fufiled double"

Solving this isn't some huge achievement. te may have solved it too, but Riku was the first to put it in Scrivere and that's what counts, especially with something so simple.
