Respuesta :
In tis question it is given that,
If x = y + 2 and y + 2 = 8, then x = 8.
Let's check out transitive property which states that
If
[tex]a=b \ and \ b=c[/tex]
Then,
[tex]a=c[/tex]
In this question,
[tex]a=x , b=y+2,c=2[/tex]
SO we can say that the given expression follows transitive property of equality .
And the correct option is the first option .
