Answer: k=8

Step-by-step explanation: Simplify k-15/7=1 to k/7 - 15/7=-1. Add 15/7 to both sides and you get k/7=8/7 so k=8!

Good luck! :)

Answer:

k = 8

Explanation:


(k-15)/(7)=-1\qquad\text{multiply both sides by 7}\\\\7\!\!\!\!\diagup^1\cdot(k-15)/(7\!\!\!\!\diagup_1)=(7)(-1)\\\\k-15=-7\qquad\text{add 15 to both sides}\\\\k-15+15=-7+15\\\\k=8
