Question

Which property justifies this statement?

If 12 = x + 5, then x + 5 = 12
A, Reflexive
B,Subtraction
C,Symmetric
D,Addition

Answer 1

If 12 = x + 5, then x + 5 = 12
It's Symmetric Property of Equality

answer is

C,Symmetric

Answer 2

we have been asked to find that which property justify the given statement.

The given statement is :

If 12 = x + 5, then x + 5 = 12

Here as we can see , that the sides have been changed.

As we know from the symmetric property that if a=b then b=a.

Using the symmetric property we can write, as its written in the given equation

If 12 = x + 5, then x + 5 = 12

Hence the correct option is C.
