One table seats six people, two tables sit together 14 people, three tables sit together 14 people ... How many people can sit in this row 10 table? If there are 38 people in a * * *, how many tables do you need to sit? Solution: According to the meaning of the problem, we rank the number of tables and the number of people who do it. 1 (Zhang) 2 (Zhang) 3 (Zhang) 4 (Zhang) ... 6 (person) 10 (person) 14 (person) 18 (person) ... two tables sit together 65438+ Four people sit 10 people sit at two tables together ... According to the above arrangement order, we can draw the following rules: each table has four more people, that is to say, a row of 10 tables, that is, nine tables, so a row can sit 10 tables: 6+9×4=42 people. If there are 38 people in a * * *, how many tables do you need to sit? Let's set up X tables. According to the above analysis, we can get the following equations: 6+4X=38, X=8. That's eight tables.
