Explanation:
This is the closest answer to the answer I got, it might be wrong and it might not. My answer was 23.8!
The given equation is:
0 + 7y + 2 = 7y + 2
This equation is showing that addition of 0 leaves the expression unchanged. 0 is known as the Additive Identity this means if we add or subtract 0 from any expression, number or equation the result won't be changed.
Therefore, the equation satisfied the property of Additive Identity of Real Numbers.
