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.

Correct answer:

a =  18 kg
b =  12 kg
c =  15 kg

Step-by-step explanation:

a=18=18 kg
b=aa/3=1818/3=12 kg

c = (18+12+c)/3

2c = 30

c = 15
