Example: 15 > 8, adding 6 to both sides, we get L.H.S. = 15 + 6 = 21 R.H.S. = 8 + 6 = 14 Since 15 > 8, 15 lies to the right of 8, after adding 6 to both sides 21 lies to the right of 14. \ 21 > 14 \ If 15 > 8 then 21 > 14 ...........I
Consider 6 > 4, adding (2) both sides, we get
From I and II we have the property  I
Example: Solve for x in the inequality x  15 > 8 x  15 + 15 > 8 + 15  adding 15 on both sides does not change the inequality x > 23 Directions: Write at least ten examples of your own and prove the above inequality property.
