<h3>Additive property of equality: Determining equivalent equations</h3>
From the question, we are to determine if the equations John wrote are equivalent.
From the given information,
John wrote that
5 + 5 = 10
Then,
He added n to both sides of the equation to get
5 + 5 + n = 10 + n
From the Additive property of equality, we have that
"<em>If we add or subtract the same number to both sides of an equation, the sides remain equal</em>."
Since, John added the same number, n, to both sides of the equation, the equations John wrote are equivalent.
