Answer:
k=9
Explanation:
8k-6=(k+3)+6k first remove the unnecsarry parentheses which would make it 8k-6=k+3+6k
then collect the like terms and get 8k-6=7k+3 then move the variable to the left and change its sign to get 8k-7k-6=3.
then collect the like terms a final time which would get you k=3+6 to then get k=9
hope this helps!
