Answer:
Large box weighs 18 kg and small boxes weighs 6.5 kg.
Step-by-step explanation:
From source, the correct question is:
Delivery of 5 large boxes and 2 small boxes has a total weight of 103 kilograms.
Delivery of 3 large boxes and 8 small boxes has a total weight of 106 kilograms.
Let the weigh of large box = x
The weigh for the small box = y
So,
5 x + 2 y = 103 - -----1
3 x + 8 y = 106 - -----2
Solving,
2y = 103 - 5 x
Applying in 2 as:
3 x + 4*(103 - 5 x) = 106
x = 18 kg
y = 6.5 kg
Thus, Large box weighs 18 kg and small boxes weighs 6.5 kg.
