Answer:

Step-by-step explanation:

9) 24=6(-x-3)

   24=-6x-18

   42=-6x

   x=-7

10) 75=3(-6n-5)

     75=-18n-15

     90=-18n

     n=-5

11) -3(1+6r)=14-r

   -3-18r=14-r

    17=-17r

    r=-1

12) 6(6v+6)-5=1+6v

    36v+36-5=1+6v

    36v+31=1+6v

    30=-30v

     v=-1

13) -4k+2(5k-6)=-3k-39

    -4k+10k-12=-3k-39

    6k-12=-3k-39

    9k=-27

     k=-3

14) -16+5n=-7(-6+8n)+3

     -16+5n=42-56n+3

     -16+5n=45-56n

     61=-61n

     n=-1
