1) In this problem, let's examine each statement or expression
8 +3 = 3 +8
11 = 11 True True, due to the Commutative Property of Addition.
2.) 2.5 +4x = 3d + 2+ 3
2.5 + 4x = 3d +5 False
There is no way to prove the validity of this statement.
3) 9 - 3h = -3h +9
-3h +3h = 9 -9
0 = 0 True
This is true by the Reflexive Property
