Answer:
C: x+8= 6
Explanation:
So if you were to work each of these out x + 6 = 8 that problem gives us positive 2, when we are looking for a -2 so that answer is ruled out. Then you go to x-6=8 you move the -6 and add it to the 8 and you get x = 14 still not our answer so thats also ruled out. Then x-8=6 is the same thing as the last one but with a -8 instead of a 6 but you get the same answer which is x=14 so not that one either. Then you work on the choice x+8=6 and you subtract 8 from both sides and you end up with a -2. So our final answer is C: X+8=6
