Trio weight

Adelka, Barunka, and Cecilka are weight in pairs. Adelka with Barunka weighs 98 kg, Barunka with Cecilka 90 kg and Adelka with Cecilka 92 kg. How much does each of them weigh?

Correct result:

a =  50
b =  48
c =  42

Solution:

a+b = 98
b+c = 90
a+c = 92

a+b = 98
b+c = 90
a+c = 92

a = 50
b = 48
c = 42
