From the given meanings of the symbols:
- \( \times \) means brother,
- \( + \) means son,
- \( - \) means mother,
- \( = \) means husband.
To express \( X \) as the father of \( Y \), we look for the correct relationship. The symbol \( X - Z + Y \) means:
- \( X - Z \) means \( X \) is the mother of \( Z \),
- \( X - Z + Y \) means \( X \) is the mother of \( Z \) and \( Y \) is the son of \( X \), which implies that \( X \) is the father of \( Y \).
Thus, the correct relationship is \( X - Z + Y \).
