1. The problem is to solve the equation and then check the solution for the number 2. 2. Since the user did not specify the exact equation, let's assume the equation is $x = 2$. 3. To check if $x=2$ is a solution, substitute $x=2$ back into the original equation. 4. If the original equation is $x = 2$, substituting $x=2$ gives $2 = 2$, which is true. 5. Therefore, $x=2$ is a valid solution. 6. If the equation is different, please provide it for a precise solution and checking.
