1. Let's start with a simple algebra problem: Solve for $x$ in the equation $$2x + 3 = 11$$. 2. The formula to solve for $x$ in a linear equation like this is to isolate $x$ on one side of the equation. 3. Subtract 3 from both sides: $$2x + 3 - 3 = 11 - 3$$ which simplifies to $$2x = 8$$. 4. Now divide both sides by 2 to solve for $x$: $$x = \frac{8}{2} = 4$$. 5. So the solution is $x = 4$. Try solving this and let me know if you want more questions or different types!
