1. The problem is to express $x$ in terms of $n$ given an equation involving $x$ and $n$. 2. To solve for $x$, isolate $x$ on one side of the equation. 3. For example, if the equation is $x + n = 0$, subtract $n$ from both sides to get $x = -n$. 4. If the equation is more complex, use algebraic operations such as addition, subtraction, multiplication, division, or factoring to isolate $x$. 5. Always perform the same operation on both sides of the equation to maintain equality. 6. Once $x$ is isolated, the expression will be in terms of $n$. 7. Without a specific equation, the general solution is $x = f(n)$ where $f$ is the function derived from the original equation.
