To solve for \( x \) when \( y = -2 \), we need a relationship or equation that connects \( x \) and \( y \). Without additional information or an equation that specifies how \( x \) and \( y \) are related, we cannot determine a specific value for \( x \).
If you have a specific equation or context in which \( y \) is defined in terms of \( x \), please provide that, and I can help you find the value of \( x \) when \( y = -2 \).
