Answer:
The first one. 5+(-7);-2
Explanation:
The start of the arrow is on positive 5, so it doesn't need a - in front of it. Then the arrow goes back 7 places, meaning it is adding onto the 5 but it is a (-7). Then the arrow ends on -2, so that would also get rid of the bottom two answers and leave the top two. Putting all of this together looks like this:
+5
+(-7)
=-2
5+(-7);-2
