Answer :

-(7c-18)-2c> 0
First you have to distribute the minus sign in order to combine like terms
EX: -7c+18-2c> 0 then combine like terms which would get you -9c and solve for c


Ex: -9c +18> 0
   then minus 18 from both sides  to get -18
Next divide -18 by -9 to have c<2 because when you divide by a negative the signs would flip
