The equation illustrates inverse property of addition.
Explanation:
The equation is
The inverse property of addition states that the sum of a negative number and the same number which is positive will always be equal to zero.
Thus, the number added to its opposite sign results in zero.
In other words, the purpose of inverse property of addition is to get the result zero after addition.
Hence, the equation illustrates inverse property of addition.
