In order to answer this we must do something that I call collecting like terms, we find all of the numbers with the same ‘unit’. For this question, we have 9k and +2k, giving us 11k. Then we look at the J, we have -6j +j, giving us -5j. Then we do +6-2, leaving us with 4.
So the final answer is 11k-5j+4
