Emily = x

Joe = x+3

Jane = 2(x+3)


The total is


    x + (x+3) + 2(x+3) = 29


    4x                 = 29 - 3 - 6 = 20

     x                              = 20/4 = 5


ANSWER.  Emily is 5;   Joe is  5+3 = 8;  Jane  is  2*8 = 16.

Solved.

Joe               j
Emily             j-3
Jane              2j
Combined          29

j%2B%28j-3%29%2B2j=29
