A barrel

A barrel of sorghum weighs 56 kg. The same barrel filled with kerosene weighs 35 kg. If sorghum is twice as heavy as kerosene, how much does the empty barrel weigh?

Final Answer:

b =  14 kg

Step-by-step explanation:

b+s=56 kg b+k=35 kg s=2k  b+2k=56 b+k=35  b+2 k=56  b+2k=56 b+k=35  Row2Row1Row2 k=21  k=121=21 b=562k=562 21=14=14 kg  b=14 k=21   Verifying Solution:  s=2 k=2 21=42 kg m1=b+s=14+42=56 kg m2=b+k=14+21=35 kg
