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

C)

Step-by-step 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.

Substitute a =2

So,

So, Option C satisfies the law

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

Only Option C is true .
