1. The problem is to solve the equation or expression given in the example. 2. Since the user asked for another example, let's consider solving a simple linear equation: $2x + 3 = 7$. 3. The formula to solve for $x$ in a linear equation $ax + b = c$ is $x = \frac{c - b}{a}$. 4. Applying this formula, we subtract 3 from both sides: $$2x + 3 - 3 = 7 - 3$$ 5. Simplifying, we get: $$2x = 4$$ 6. Now divide both sides by 2: $$\frac{\cancel{2}x}{\cancel{2}} = \frac{4}{2}$$ 7. This simplifies to: $$x = 2$$ 8. Therefore, the solution to the equation $2x + 3 = 7$ is $x = 2$.
