1. The problem is to solve the inequality $Y < -2$. 2. This inequality states that the variable $Y$ must be less than $-2$. 3. There is no further simplification needed because the inequality is already solved for $Y$. 4. The solution set includes all real numbers less than $-2$. 5. In interval notation, the solution is $(-\infty, -2)$. 6. This means any value of $Y$ smaller than $-2$ satisfies the inequality.
