Brought 5796

Kamil and Kamila brought a total of 140 kg of paper. Kamila weighed 30 kilograms less than Kamil. How much Kamil brought, and how much was Kamila?

Correct answer:

a =  55
b =  85

Step-by-step explanation:


a+b = 140
a = b-30

a+b = 140
a-b = -30

Row 2 - Row 1 → Row 2
a+b = 140
-2b = -170


b = -170/-2 = 85
a = 140-b = 140-85 = 55

a = 55
b = 85
