Let's start with a general equation where you have a term \(-2n\) on the right side:
\[ A = -2n + B \]
To eliminate \(-2n\) from the right side, you can add \(2n\) to both sides of the equation:
\[ A + 2n = -2n + B + 2n \]
On the right side, the \(-2n\) and \(+2n\) cancel each other out:
\[ A + 2n = B \]
Now, all the \(n\) terms are on the left side of the equation. If you started with a specific equation and want to adjust it in this way, feel free to share it, and I can provide further assistance!
