(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 jaar they were 24 and 12.

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

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