Question 230879
Hello, 
Let's represent x for the number of men. Therefore we can let 3x represent kids and 2x represent women. There's a total of 138 people so we can write an equation.

                  x + 3x + 2x = 138

Combine like terms: 

                     6x = 138

Divide both sides by 6:

                      x = 23

Therefore there are   23 Men
                      69 kids
                      46 women

This adds up to 138 people. :-)
