Question

Which property justifies this statement?

"If 7 = x + 4, then x + 4 = 7."

A.
commutative

B.
symmetric

C.
associative

D.
transitive

Answer 1

symmetric if left = right then right =left i would say

Answer 2

?

Answer 3

commutative is talking about the order in an expression
that is this property looks like this: a+b = b+a
(the order in the expression changes)


symmetric is talking about all one direction equality implies the other direction of equality
that is this property looks like this: a=b implies b=a


associative is talking about the grouping changing in the expression
that is this property looks like this: (a+b)+c = a+(b+c)


transitive is talking about how two different certain equalities imply another
that is this property looks like this: a=b and b=c implies a=c

Answer 4

SO symmetric

Answer 5

yeah

Answer 6

I would go with symmetric. :)

Answer 7

that is what @jamaica25 was trying to say
she was calling the left hand expression of the equality left
and the right hand expression of the equality right

that is we have 7=x+4
so 7 is the left hand expresssion (she called just left)
and x+4 is the right hand expression (she called right)

so she said left=right implies right=left
which is the exactly the symmetric property
