1. The problem is to solve an equation step by step and learn the process. 2. Since no specific equation is given, let's consider a simple example: Solve for $x$ in the equation $2x + 3 = 7$. 3. The formula or rule used 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: $$2x + 3 - 3 = 7 - 3$$ which simplifies to $$2x = 4$$ 5. Next, divide both sides by 2 to solve for $x$: $$\frac{\cancel{2}x}{\cancel{2}} = \frac{4}{2}$$ which simplifies to $$x = 2$$ 6. So, the solution is $x = 2$. 7. This process shows how to isolate the variable by performing inverse operations step by step, which is a fundamental skill in algebra.
