Question: Give me an example
1. The user asked for an example, but no specific math problem was provided.
2. To provide a useful example, let's consider a simple algebra problem: Solve for $x$ in the equation $$2x + 3 = 7$$.
3. The formula used here is to isolate $x$ by performing inverse operations.
4. Step 1: Subtract 3 from both sides:
$$2x + 3 - 3 = 7 - 3$$
$$2x = 4$$
5. Step 2: Divide both sides by 2:
$$\frac{\cancel{2}x}{\cancel{2}} = \frac{4}{2}$$
$$x = 2$$
6. Therefore, the solution is $x = 2$.
7. This example demonstrates solving a linear equation by isolating the variable.
