x, number of sisters
y, number of brothers

Each brother or sister excludes himself or herself in his or her counting of the other gendered siblings.

The x equation is what the brother says; and the y equation is what the sister says.

Did this interpretation work?

Return to the system and take

This family has 9 girls (the sisters) and 5 boys (the brothers).
