What is the value of $n$ in the equation $n + (n + 1) + (n + 2) = 9$?
To solve for $n$, I need to simplify the equation and isolate $n$ on one side. First, I can combine the like terms on the left side by adding the $n$'s and the constants separately. That gives me $3n + 3 = 9$. Next, I can subtract $3$ from both sides to eliminate the constant term on the left. That gives me $3n = 6$. Finally, I can divide both sides by $3$ to get $n$ by itself. That gives me $n = 2$.
