Question

Which property justifies this statement?

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

A.
transitive

B.
commutative

C.
symmetric

D.
associative

Answer 1

I know the definitions:

Associative property is a property of some binary operations.

Transitive if whenever an element a is related to an element b.

Having, involving, or exhibiting symmetry.

Commutative if changing the order of the operands does not change the result.

Answer 2

some of these definitions might be from a different context, especially "symmetric"
for equality, symmetric means \[A=B\iff B=A\]

Answer 3

Ohhh, then the answer would be C, correct? :3

Answer 4

in other words, the equal sign reads from left to right and also from right to left, so \[2+3=5\] is the same as \[5=3+2\]

Answer 5

yeah C

Answer 6

Thank you!
