# Bob and Bobek

Bobek has 2 cabbages and 5 carrots, Bob has 2 cabbages and 9 carrots. When Bobek stepped on the scale weight 5800 g and when Bob weight 8960 g. Actual Bob weight is 8 kg and Bobek 5 kg. How much weighs one carrot?

Correct result:

m =  40 g

#### Solution:

2z + 5m = 5800-5000
2z + 9m = 8960-8000

2•z + 5•m = 5800-5000
2•z + 9•m = 8960-8000

5m+2z = 800
9m+2z = 960

m = 40
z = 300
