1. The problem is to create a quiz question for you. 2. Since you requested a quiz, here is a simple algebra question: **Question:** Solve for $x$ in the equation $$2x + 3 = 11$$. 3. The formula used here is to isolate $x$ by performing inverse operations. 4. Step 1: Subtract 3 from both sides: $$2x + 3 - 3 = 11 - 3$$ $$2x = 8$$ 5. Step 2: Divide both sides by 2: $$\frac{2x}{\cancel{2}} = \frac{8}{\cancel{2}}$$ $$x = 4$$ 6. The solution is $x = 4$. This is a basic linear equation solving problem.
