1. **Stating the problem:** We need to solve the equation or expression given by the user. Since no specific problem was provided, let's consider a simple example: solve for $x$ in the equation $2x + 3 = 7$. 2. **Formula and rules:** To solve linear equations like $ax + b = c$, we isolate $x$ by performing inverse operations. 3. **Step-by-step solution:** - Start with the equation: $$2x + 3 = 7$$ - Subtract 3 from both sides: $$2x + \cancel{3} - \cancel{3} = 7 - 3$$ $$2x = 4$$ - Divide both sides by 2: $$\frac{2x}{\cancel{2}} = \frac{4}{\cancel{2}}$$ $$x = 2$$ 4. **Explanation:** We first removed the constant term on the left by subtracting 3 from both sides. Then, to isolate $x$, we divided both sides by the coefficient 2. This gives the solution $x=2$. This method works for any simple linear equation. **Final answer:** $x = 2$
