Answer:
-17 / 2
Step-by-step explanation:
First, find out what x is:
2x + 7 = -10
2x = -10 - 7
2x = -17
x = -17 / 2
I'm not sure if there's a mistake on the question, but if you plug in every number none of them work. Maybe try talking it out with your teacher!
If you plug in -34 you get -61 = -10.
If you plug in 34 you get 75 = -10.
If you plug in 6 you get 19 = -10.
If you plug in -6 you get 5 = -10.
