Question

Need help with Algebra Properties
This is Algebra I Problem

Answer 1

13x-9-6x=13x+(-9)+(-6x) definition of subtraction
=13x +(-6x) +(-9) Commutative property (?)
=[13x+(-6)x]+(-9) Associative property (?)
=[13+(-6)]x +(-9) need help with this one
7x+(-9) Simplify
7x-9 Definition of Subtraction

Answer 2

i believe that would be "factoring"

Answer 3

I don't believe that property has been taught yet

Answer 4

I believe only associative, commutative and distributive have been taught at this point. Just trying to help my tadpole do his math homework.

Answer 5

13x-9-6x=13x+(-9)+(-6x) definition of subtraction
=13x +(-6x) +(-9) Commutative property (?)
=[13x+(-6)x]+(-9) Associative property (?)
=[13+(-6)]x +(-9) Distributie property
7x+(-9) Simplify
7x-9 Definition of Subtraction

Answer 6

ok I will go with that one. But we all know later on it is really factoring.......lol
