Hi,

[tex]\dfrac{2c}{3}+1\ \textgreater \ 7\\\\3\times\left(\dfrac{2c}{3}+1\right)\ \textgreater \ 3\times7\\\\2c+3\ \textgreater \ 21\\2c\ \textgreater \ 21-3\\2c\ \textgreater \ 18\\\\c\ \textgreater \ \dfrac{18}{2}\\\\c\ \textgreater \ 9[/tex]

c > 9
Alright, now this is the work. 
2*c/3+1-(7)>0
Alright and if you solve it, you get an inequality of c>9
I really, really hope this helps :)
