1. The problem is to solve the equation or expression given by the user, but since no specific problem was provided, I will demonstrate solving a simple algebraic equation as an example. 2. Let's solve the equation $2x + 3 = 7$. 3. The formula used here is to isolate the variable $x$ by performing inverse operations. 4. First, subtract 3 from both sides: $$2x + 3 - 3 = 7 - 3$$ which simplifies to $$2x = 4$$ 5. Next, divide both sides by 2 to solve for $x$: $$\frac{2x}{2} = \frac{4}{2}$$ which simplifies to $$x = 2$$ 6. Therefore, the solution to the equation $2x + 3 = 7$ is $x = 2$. This method applies to linear equations where the goal is to isolate the variable on one side of the equation.
