An equation is shown below: 4(x − 3) − 5(x + 1) = 3 which of the following algebraic properties is not needed to solve this equation? distributive property addition property of equality commutative property of addition transitive property

Distributive property YES: 4(x - 3) = 4x - (4)(3)

Addition property YES: 
4x - 12 - 5x - 5 = 3
-x - 17 = 3
(-x - 17) + 17 = 3 + 17
-x = 20

Commutative property YES: 
4x - 12 - 5x - 5 = 3
4x - 5x - 12 - 5 = 3

Transitive property NO:
if a = c and b = c then a = c

21/2 or 5/2
