1. The problem is to create a test question or example problem. 2. Since no specific topic or question is given, let's create a simple algebra problem: Solve for $x$ in the equation $2x + 3 = 7$. 3. The formula to isolate $x$ is to subtract 3 from both sides and then divide both sides by 2. 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 to the equation $2x + 3 = 7$ is $x = 2$.
