Question

Which property justifies this statement?

X - 4 = x - 4
A,substition property of equality
B,transitive property of equality
C,symmetric property of equality
D,reflexive property of equality

Answer 1

X - 4 = x - 4

answer
D,reflexive property of equality

reflexive property of equality is equal itself

Answer 2

reflexive property of equality

Explanation:

A: substitution property of equality

`y=x+5, x=2`

`y=2+5=7` is an example of substitution property.

B:transitive property of equality

If c=b and b=5 then c=5

`x - 4 = x - 4` does not represent transitive property

C:symmetric property of equality

1+2=3 then 3=1+2 is symmetric.

`x - 4 = x - 4` does not represent symmetric property

D:reflexive property of equality

a=a represents reflexive property

`x - 4 = x - 4` represents reflexive property of equality
