Question

If you could explain what property is illustrated in this equation:
5(3x+y)=5(3x+1y)

Answer 1

Well the only thing that changes is that you have \(1y\) instead of \(y\). So what's the property that tells you that \(1y=y\)?

Answer 2

Identity? I have no clue what the property is. :/ Trying so hard to remember but nothing comes to mind

Answer 3

Multiplicative identity?

Answer 4

I don't have a specific "property" come to mind except for the existence of the multiplicative identity. Which happens to be denoted by 1.

Answer 5

alright, that then confirms what I am thinking :)

Answer 6

Excellent.

Answer 7

One more quick question tho..
on
(19a+11b)+0=19a+11b

would that be additive identity?

Answer 8

That's what I would say.

Answer 9

Ok thanks!!! If anyone else could add their two cents, I would appreciate that as well :)
