Distribute the 1/7 to 14r and -56 which gets you 2r-8=-14. After that subtract 8 from both sides, then you will have 2r=-6. Divide both sides by 2 the you will have your answer r=-3.

The Associative Property say that it doesn't matter how we group the numbers (i.e. which we calculate first) when we add

(a + b) + c = a + (b + c)

The Commutative Property say we can swap numbers over and still get the same answer when we add

a + b = b + a

The Distributive Property:

a(b + c) = ab + ac

------------------------------------------

-3a + 4b + 5a + (-7b) = -3a + 5a + 4b + (-7b)

<h3>Answer: the commutative property</h3>
