1. The problem is to create a math question for practice. 2. Let's consider a simple algebra problem: Solve for $x$ in the equation $$2x + 3 = 11$$. 3. The formula used here is to isolate $x$ by performing inverse operations. 4. First, subtract 3 from both sides: $$2x + 3 - 3 = 11 - 3$$ $$2x = 8$$ 5. Next, divide both sides by 2 to solve for $x$: $$\frac{\cancel{2}x}{\cancel{2}} = \frac{8}{2}$$ $$x = 4$$ 6. So, the solution to the equation is $x = 4$. This is a basic linear equation solving problem suitable for beginners.
