What we simply did is to substitute RS for XY in the second equation;
The correct answer is Substitution property
It can be fully referred to as the substitution property of equality.
What it simply means in a nut shell is that since XY and RS are equal, then in any addition or arithmetic equation, we can make a substitution of XY for RS since they are equal to each other
