The step \( 12 = x + 5 \) becomes \( x + 5 = 12 \) using the **Symmetric Property of Equality**.
Solución
The step from \( 12 = x + 5 \) to \( x + 5 = 12 \) is justified by the **Symmetric Property of Equality**.
**Symmetric Property of Equality** states that if one quantity equals another, then the second quantity equals the first. In other words, if \( a = b \), then \( b = a \).
**Explanation of Other Properties:**
- **Addition Property of Equality:** Allows you to add the same number to both sides of an equation. For example, if \( a = b \), then \( a + c = b + c \).
- **Subtraction Property of Equality:** Allows you to subtract the same number from both sides of an equation. For example, if \( a = b \), then \( a - c = b - c \).
- **Reflexive Property of Equality:** States that any quantity is equal to itself. For example, \( a = a \).
**Correct Property:**
- **Symmetric Property of Equality**

The Deep Dive
Did you know that the Symmetric Property of Equality states that if one quantity equals another, then you can swap them? So, if \( 12 = x + 5 \), it naturally follows that \( x + 5 = 12 \). It’s a simple flip, like magic in algebra! When solving equations, it's easy to make mistakes. One common pitfall is forgetting to keep an equation balanced when performing operations. Always remember: whatever you do to one side of the equation, you must do to the other! This ensures that the equality remains true—a key to avoiding those pesky errors!
