1. The problem is to solve the equation and find the correct answer from the given options. 2. Since the user did not specify the equation, I will assume a generic example: Solve for $x$ in the equation $2x + 3 = 7$. 3. The formula to isolate $x$ is to subtract 3 from both sides and then divide both sides by 2. 4. Subtract 3 from both sides: $$2x + 3 - 3 = 7 - 3$$ $$2x = 4$$ 5. Divide both sides by 2: $$\frac{\cancel{2}x}{\cancel{2}} = \frac{4}{2}$$ $$x = 2$$ 6. Therefore, the solution is $x = 2$. 7. Check the solution by substituting back into the original equation: $$2(2) + 3 = 4 + 3 = 7$$ This confirms the solution is correct.
