1. Let's start with a simple algebra quiz question to test your understanding. 2. Solve for $x$ in the equation $$2x + 5 = 15$$. 3. To solve for $x$, we use the rule of isolating the variable by performing inverse operations. 4. First, subtract 5 from both sides: $$2x + 5 - 5 = 15 - 5$$ $$2x = 10$$ 5. Next, divide both sides by 2 to isolate $x$: $$\frac{2x}{\cancel{2}} = \frac{10}{\cancel{2}}$$ $$x = 5$$ 6. So, the solution is $x = 5$. 7. Please try solving this and let me know your answer so I can correct it if needed.
