1. **Stating the problem:** You asked for a question and its answer. 2. **Question:** Solve for $x$ in the equation $$2x + 3 = 7$$. 3. **Formula used:** To solve a linear equation, isolate $x$ by performing inverse operations. 4. **Step-by-step solution:** - Subtract 3 from both sides: $$2x + 3 - 3 = 7 - 3$$ $$2x = 4$$ - Divide both sides by 2: $$\frac{\cancel{2}x}{\cancel{2}} = \frac{4}{2}$$ $$x = 2$$ 5. **Answer:** The solution is $x = 2$. This means when $x$ is 2, the equation $2x + 3 = 7$ holds true.
