1. The problem is to find the answer to the user's query "answer" which is ambiguous, so let's interpret it as solving a simple algebraic expression or equation. 2. Since no specific problem is given, let's consider a basic example: Solve for $x$ in the equation $2x + 3 = 7$. 3. The formula used is to isolate $x$ by performing inverse operations. 4. Subtract 3 from both sides: $$2x + 3 - 3 = 7 - 3$$ which simplifies to $$2x = 4$$. 5. Divide both sides by 2: $$\frac{2x}{2} = \frac{4}{2}$$ which simplifies to $$x = 2$$. 6. Therefore, the solution is $x = 2$. 7. This method applies to linear equations where the goal is to isolate the variable on one side.
