There are several three legged stools and four legged chairs, and they are all manned. If there are 39 legs, how many people are there?

39-6 * 6 = 3, 3 / 5 is not an integer, 39-6 * 5 = 9, 9 / 5 is not an integer, 39-6 * 4 = 15, 15 / 5 = 3, so there are 4 chairs with 4 legs, 3 stools with 3 legs, 4 + 3 = 7 people

There are 18 chairs with 4 legs and 3 legs in a storage room. There are 65 chair legs and stool legs. How many chairs? How many stools?

If there are x chairs, there are 18-x benches. A: there are 11 chairs and 7 benches

A stool has three legs and a chair has four legs. There are 35 legs in all. How many seats, chairs and people are there

One stool, five chairs, six people
