Question

1. Look at the Properties Table. The Symmetric property is important to know when solving an equation. Which example is used in the table for the Symmetric property?
A. x + 3 = 5 then x = 2
B. 7n - 2 = 4 can be written as 4 = 7n - 2
C. 5 = 5
D. If I know that 4x - 3c and 3c = 50, then 4x = 50.

Answer 1

\[
\text{The symmetric property states that an equality is bidirectional, i.e.}\\
\ \ \ a=b\iff b=a\\
\text{We see this exhibited in option B.}\\
\ \ \ 7n-2=4\iff4=7n-2
\]

Answer 2

b

Answer 3

or c?

Answer 4

C is not demonstrating symmetry of an equality, it's just showing the reflexive property ;-)

Answer 5

oh ...lol so b then
