If 10 + a = 10, then a = 0

which property is demonstrated by the example?
a) substitution
b) identity property for addition
c) multiplicative property of zero
d) inverse property for multiplication

B) identity property of addition.

Step-by-step explanation:

Given:

The statement given is:

Here, we observe that 10 is added to a giving the number 10 itself as the answer. So, we know of a property which says that when 0 is added to a number, the result is the number itself. This property is called identity property of addition.

So, the value of must be 0 because on adding to 10, we are getting the number 10 only. So, the above statement is an example of identity property of addition.
