1. Let's start by stating the problem: We need to determine if $x = -1$ is the correct solution for the given equation or problem (which is not explicitly provided). 2. Since the original equation is not given, the best approach is to substitute $x = -1$ into the equation and check if it satisfies the equation. 3. If the equation is $f(x) = 0$, then substitute $x = -1$ and evaluate $f(-1)$. 4. If $f(-1) = 0$, then $x = -1$ is a correct solution. 5. If $f(-1) \neq 0$, then $x = -1$ is not a solution. Please provide the original equation or problem to verify if $x = -1$ is the right answer.
