7n-2(n+5)< 3n-16 7n-2n+10<3n-16      Distribute the 2 into n+5    5n+10<3n-16          Subtract like figures 5n-3n+10<3n-3n-1  Subtract 3n from each side. (You want the variable on ONE side.) 2n+10-10<-16-10     Isolate the variable. Negative plus negative= bigger negative. 2n/2< -26/2             Negative divided by positive= smaller negative. Divide by 2 to isolate. n<-13
