What does the Symmetric Property of Equality states? 

• If numbers are equal, they will still be equal if the order is changed. 
• If numbers are equal to the same number, then they are equal to each other.
• If two numbers are equal, then substituting one in for another does not change the equality of the equation. 
• Subtracting the same number from
