Question

identity and equalty properties
name the property used in each equation. then find the value of n.
p.s please just give me the complete anwser (:

n+0=19

Answer 1

i guess it just uses the additive identity?.. anything plus zero equals itself so n=19

Answer 2

The property for that equation is the "Additive Identity" property. Adding 0 to anything doesn't change the problem. So . . .

n+0 = 19
n = 19

If you have to show some sort of work for this problem, all your doing is solving for n.
So you just subtract 0 from 19, and of course are left with 19.
Hence n = 19.
