1. The problem is to understand the phrase "User: with example" and provide a relevant example. 2. Since the user message is not a clear math problem, let's interpret it as a request for an example of a math problem and solution. 3. Example: Solve the equation $2x + 3 = 7$. 4. Use the formula for solving linear equations: isolate $x$ by subtracting 3 from both sides and then dividing by 2. 5. Step-by-step: - Subtract 3: $2x + 3 - 3 = 7 - 3$ which simplifies to $2x = 4$. - Divide both sides by 2: $x = \frac{4}{2} = 2$. 6. Therefore, the solution is $x = 2$. This example shows how to solve a simple linear equation by isolating the variable.
