Answer :
Answer
large: 18.25 kg
small: 13.5 kg
Step-by-step explanation:
We can use l and s to represent the weights of large and small boxes, respectively. Then the given relations are ...
4l +8s = 181
2l +3s = 77
Subtracting twice the second equation from the first gives ...
(4l +8s) -2(2l +3s) = (181) -2(77)
2s = 27
s = 13.5
Using this in the first equation, we have ...
4l +8(13.5) = 181
4l = 73
l = 18.25
A large box weighs 18.25 kg; a small box weighs 13.5 kg.
