The students went on a spring outing, 80 of them brought water bottles, 70 of them brought fruits, and 6 of them didn't bring either. If the number of people who bring both water bottles and fruits is half of all the students who participated in the spring outing, how many students participated in the spring outing?
同学们去春游，带水壶的有80人，带水果的有70人，两样都没带的有6人．若既带水壶又带水果的人数是所有参加春游人数的一半，则参加春游的同学共有多少人．
