Did I do this correctly?
13  (2c + 2) >(pretend it has the line under it that means greater than or equal to) 2(c + 2) + 3c
13 2c 2 (greater than or equal to) 5c + 4
11c (greater than or equal to) 7c + 4
7c to both sides
4c (greater than or equal to) 4
divide both sides by 4
c is greater than or equal to 1
Thanks!

13(2c+2)>= 2(c+2)+3c
132c2>=5c+4
11>=7c+4(((((this varies from yours, from here onward))))
7>=7c
c is less than or equal to 1

How did you get the 7 > 7c?

If you follow my work, you get it. I subtracted 2 from 13 to get 11, then subtacted 4 from both sides.

Thank you! I don't know why I didn't see that.
