Question

Look at the equations.

If 3a + 2(b − 2c) = p then p = 3a + 2(b − 2c)

Which property is used to write the equations?

associative property of addition

distributive property of equality

reflexive property of equality

commutative property of addition

Answer 1

hmm seems odd as there should be "symmetric property of equality" in there as well (as that's the real answer)

Answer 2

if those are the true answer choices, then the closest thing is "reflexive property of equality"

Answer 3

but that's not the true answer in my opinion

Answer 4

Why?? and thank you

Answer 5

the reflexive property is you have something trivial (yet important) like x = x (basically some number always equals itself)


The symmetric property is what you really want and it says

if x = y, then y = x

Answer 6

The symmetric property allows you to flip the sides of any equation. So you can go from 2 = x to x = 2

Answer 7

Ohhhhhh I got it. I see the difference

Answer 8

yes it's very subtle, but you probably could make the argument that the reflexive property can be used here.
