The answer would be: k= 1/3
Here’s how you solve it!
First you want to divide both sides by 2
Now you are left with this:
3k+4=5
Now you want to move 4 to the other side causing it to change into a negative.
3k=5-4
Now subtract 5-4 to get 1
3k= 1
Now divide both sides by 3
K= 1/3
Now you are left with your answer: 
Hope this helps! :3
