Question

Which property justifies this statement?

Answer 1

X - 4 = x - 4

answer
D,reflexive property of equality

reflexive property of equality is equal itself

Answer 2

Answer:

reflexive property of equality

Step-by-step 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
