Question

3 + a = y is the same as y = 3 + a. This is an example of which algebraic property?

Answer 1

commutative property of addition

Answer 2

Thank you!

Answer 3

no problem

Answer 4

I dont think it is
commutative says
a+b=b+a

Answer 5

Are you sure?

Answer 6

yes im sure
but im not sure what one they are asking for
maybe its this
if a = b
the b = a
this property is called symmetry

Answer 7

maybe this site will be more helpful http://www.mathsisfun.com/associative-commutative-distributive.html

Answer 8

that site does not have the property that is being used here
it is not commutative because it has 3+a in the same order (not a+3)
its not associative of distributive....

it is the "symmetric property of equality"

Answer 9

oh my apology

Answer 10

its more of a "relation" property than an "algebraic" property but....
