The devils

The devils weighed in hell with Dorota. They found that Dorota and the two devils weigh 250 kg together and Dorota and the four devils weigh 426 kg. All the devils weigh the same. How Much Does Dorota Weigh?

Result

d =  74 kg

Solution:


d+2c = 250
d + 4c = 426

2c+d = 250
4c+d = 426

c = 88
d = 74
