Use the commutative property of addition to simplify 12x - 36 - 6x.
nexus9112 [7]

12x - 36 - 6x \ is \ simplified \ to \ 6(x-6)

<h2>Explanation:</h2>

The commutative property of addition states that:

a+b=b+a

So applying this property to our expression we have:

12x - 36 - 6x=-6x+12x-36 \\ \\ \\ So \ here: \\ \\ a=12x-36 \\ \\ b=-6x \\ \\ \\ Combining \ like \ terms: \\ \\ 12x - 36 - 6x=6x-36 \\ \\ \\ Common \ factor \ 6: \\ \\  12x - 36 - 6x=6(x-6) \\ \\ \\ Finally: \\ \\ 12x - 36 - 6x \ is \ simplified \ to \ 6(x-6)
