Bags

The first bag has a weight of 18 kg, the second bag is a one-third lighter than the first and the third bag has three times less the weight of all three bags together. Determine their weights.

Result

a =  18 kg
b =  12 kg
c =  15 kg

Solution:

Solution in text a =
Solution in text b =

c = (18+12+c)/3

2c = 30

c = 15
