Answer:

1. k=-9

2. a=-12

Step-by-step explanation:

1. -12(k+4)=60

use distributive property

   -12k-48=60

add 48 to both sides

   -12k=108

divide both sides by -12

   k=-9

2. 8(3a)=9(2a-4)

   use distributive property

   24a=18a-36

   subtract 18a on both sides

  6a=-36

  divide both sides by 6

   a=-12
