If there are 5 children and child A+B=119 , A+C=123 , A+D=126 , A+E=129 what is the weight of child A?

I need help finding child A's weight

There isn't enough information to get a unique solution.  There are 5 unknowns, but we only have 4 equations.  Are you sure there ins't another subtle piece of information in the problem description?

Some other relationships
B + 4 = C
B + 7 = D
B + 10 = E
C + 3 = D
C + 6 = E
D + 3 = E
 
Can you solve using this system?

Actually A could have a unlimited number of weights. For example, here are two.
  A     B    C    D    E
100   19   23   26  29
  50   69   73   76  79
