Question

Which one of the following equations illustrates the commutative property?

A) 8 + 3 = 4 + 7
B) If 3 + 5 = a, then a=3+5
C) 2 + b = b + 2
D) 3(2 + 5) = 6 + 15

Answer 1

It's C). 2+b=b+2


HOPE THIS HELPS!!!!

Answer 2

C)
`2 + b = b + 2`

Explanation:

We are supposed to find which equations illustrates the commutative property.

Commutative property : The "Commutative Laws" say we can swap numbers over and still get the same answer i.e.

`a+b=b+a`

Substitute a =2

So,
`2+b=b+2`

So, Option C satisfies the law

Option A , B and D does not satisfies the law .

Only Option C is true .

`2 + b = b + 2`
