Answer:
See below.
Step-by-Step Explanation:
5)<em> 8x+9-6x-7</em>
8x + 2 - 6x (Subtract the numbers)
2x + 2 (Combine like terms)
2 (x + 1) (Common factor - Factor by grouping twice)
6) <em>2y-6+5y+9</em>
2y + 3 + 5y (Add the numbers)
7y + 3 (Combine like terms)
7) <em>3x+8+4x-9</em>
3x - 1 + 4x (Subtract the numbers)
7x - 1 (Combine like terms)
8) <em>9y+16-12y+24</em>
9y + 40 - 12y (Add the numbers)
-3y + 40 (Combine like terms)
9) <em>7g-5-8g+12</em>
7g + 7 - 8g (Add the numbers)
-g + 7 (Combine like terms)
10)<em> 11c-8+5c-8</em>
11c - 16 + 5c (Subtract the numbers)
16c - 16 (Combine like terms)
16 (c - 1) (Common factor - Factor by grouping twice)
11) <em>5(2x + 3) (This one was a bit blurry, I am assuming that's a addition sign.)</em>
10x + 15 (Distribute)
12) <em>5(-2x+3)</em>
-10x + 15 (Distribute)
