Here are the steps. You shouldn't have any trouble
writing down the work and finding the solution.
#1). Write the equation. 5 - 6k = 8
#2). Add 6k to each side of the equation.
#3). Subtract 8 from each side.
#4). Divide each side by 6 .
At this point, the solution jumps out at you.
If you don't get -1/2 , go through it again.
It's more important for your math teacher to correct your work,
not mine. I finished middle school in 1955, and now I'm e-mailing
with the daughter of my 9th grade Algebra teacher, who is a very
successful lawyer back in my home town.
