Answer:
C. 7+2n=-3 n=-5
Explanation:
By reading it out and typing it out simultaneously, you can find this.
Since it says seven added to, A and B are not options.
By adding 7+2(5) you get 17, by 7+10
By entering -5 to 7+2(-5)
You get -3 because 2(-5) is -10 and -10+7 is -3
So, C. 7+2n=-3 n=-5 is correct
