1. The problem is to solve the equation or expression involving the number 8. Since the user only said "Solve number 8," we interpret this as solving the equation $x=8$ or simply identifying the value 8. 2. If the problem is to solve for $x$ when $x=8$, the solution is straightforward: $x=8$. 3. There are no additional steps or simplifications needed because the number 8 is already a solution. Final answer: $8$
