You can put this solution on YOUR website! -5k-19=5-13k
you want to get all k's on one side and all lone numbers on the other.
add 13k to both sides
13k-5k-19=5
add 19 to both sides
13k-5k=5+19
now combine
(13-5)k=5+19
I will leave the subtraction and addition and then the next step division for you
