1. The problem is to solve an algebraic equation exactly without using a calculator. 2. Since the user did not specify the equation, let's consider a common example: Solve $2x + 3 = 7$. 3. Start by subtracting 3 from both sides to isolate the term with $x$: $$2x + 3 - 3 = 7 - 3$$ which simplifies to $$2x = 4$$. 4. Next, divide both sides by 2 to solve for $x$: $$\frac{2x}{2} = \frac{4}{2}$$ which gives $$x = 2$$. 5. The solution to the equation $2x + 3 = 7$ is $x = 2$. If you have a specific equation you'd like solved, please provide it!
