Answer:
One Solution K= -1
Explanation:
You start with -18-6k=6(1+3k)
Then you distribute 6 and get -18-6k=6+18k
Then combine like terms on both sides of the equation by adding 18 to both sides, and adding 6k on both sides. Now you should have 0=24k+24
Then you want to isolate the term with k by subtracting 24, now it should be -24=24k
Now divide 24 from both sides because it is connected with multiplication, and you get K= -1. This is one solution
