To get rid of denominators, multiply by (6•7) on both sides.
This yields: 7(-3y+15)=6(2y+4)
-21y+105=12y+24
105-24=12y+21y
81=33y
Y=27/11

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:

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