1. Let's start by understanding the problem: you want to solve a math problem step by step. Since no specific problem was given, I'll demonstrate solving a simple algebraic equation step by step. 2. Consider the equation: $$2x + 3 = 11$$. Our goal is to find the value of $x$. 3. The formula or rule we use here is to isolate the variable $x$ by performing inverse operations. 4. First, subtract 3 from both sides to get rid of the constant term on the left: $$2x + 3 - 3 = 11 - 3$$ which simplifies to $$2x = 8$$ 5. Next, divide both sides by 2 to solve for $x$: $$\frac{2x}{2} = \frac{8}{2}$$ which simplifies to $$x = 4$$ 6. So, the solution to the equation is $x = 4$. This step-by-step approach helps you isolate the variable and solve the equation systematically.
