-16/15
Step-by-step explanation:
ok let's break this down.
6 (4+7k) = 6*4 + 42k (use distributive property)
3k - 6 (4+k) = 3k - 24 - 6k (do the same thing)
24 + 42k = 3k - 24 - 6k (let's simplify this a bit)
24+42k = - 24-3k (add 3k on both sides)
24+45k=-24 (subtract 24 on both sides)
45k = - 48
k = - 48/45 or - 16/15
