1. **State the problem:** Solve the equation or expression given by the user. Since no specific equation was provided, let's consider a general approach to solving algebraic equations. 2. **General formula and rules:** To solve an equation, we aim to isolate the variable on one side. Key rules include: - You can add or subtract the same value from both sides. - You can multiply or divide both sides by the same nonzero value. - When dividing, show cancellation explicitly. 3. **Example:** Suppose we solve $2x + 3 = 7$. 4. **Step 1:** Subtract 3 from both sides: $$2x + 3 - 3 = 7 - 3$$ $$2x = 4$$ 5. **Step 2:** Divide both sides by 2: $$\frac{\cancel{2}x}{\cancel{2}} = \frac{4}{2}$$ $$x = 2$$ 6. **Explanation:** We isolated $x$ by undoing addition and multiplication step-by-step. 7. **Final answer:** $x = 2$
