Important Rule: if two inequalities have inequality symbols facing the same direction, we can add the inequalities
For example: 4 < 7 and 1 < 10
So, we can add them to get: 4 + 1 < 7 + 10
Since x > y and a > b have inequality symbols facing the same direction, we can add the inequalities to get: x + a > y + b
Answer: D

With the same inequality sign, we can arrange add one inequality to the other
x > y
a > b
x + a > y + b (Correct Answer: D)
