1. The problem is to solve the equation or expression given in option 1. Since the user did not specify the exact problem, I will assume a generic example to demonstrate the process. 2. Let's consider the problem: Solve for $x$ in the equation $2x + 3 = 7$. 3. Subtract 3 from both sides to isolate the term with $x$: $$2x + 3 - 3 = 7 - 3$$ $$2x = 4$$ 4. Divide both sides by 2 to solve for $x$: $$x = \frac{4}{2}$$ $$x = 2$$ 5. Therefore, the solution to the equation $2x + 3 = 7$ is $x = 2$. If you have a specific problem for option 1, please provide it for a detailed solution.
