Answer:
No
Step-by-step explanation:
The inequality will not be the same if the same amount is added both sides.
The addition property states that if the same quantity is added to both sides, then the inequality still remains true. Take for example:
let x, y, and z be real numbers. It follows that:
if x ≥ y, then x + z ≥ y + z
This holds true for whatever value of z
If x ≤ y, then x + z ≤ y + z
The inequality remains true.
