Answer:
the answer should be 19j-13k because first all remember when we are dealing with this expressions or problems we need to add or subtract like terms that for example it could be 2j and 17j and 11k and 2k.
2j-11k+17j-2k=
2j+17j= 19j -11k-2k= 13k so the answer is 19j-13k and remember this is the final answer because we cannot add numbers that have different variables or letters so hopefully that is the correct answer and have a great day.
