Answer:
x = -2
Step-by-step explanation:
x+8 = 2x +10
-2x + x = 10-8
-x = 2
divide both side by -1
answer -- x = -2
I think that it's B, y = -x - 7 because first you'd subtract y to get it on the other side then add x and then you'd need to make the y positive so you would divide x + 7 by -1 and that would make it y = -x - 7.
The answer is A.120
Because 60+60 +60 is 180
180-60 is 120
