1. **Problem:** If $x + 2 = 4$, find the value of $x$. 2. **Formula:** To solve for $x$, use the property of equality: subtract the same number from both sides. 3. **Step:** Subtract 2 from both sides: $$x + 2 - \cancel{2} = 4 - \cancel{2}$$ 4. **Simplify:** $$x = 2$$ 5. **Answer:** The value of $x$ is 2.
