A delivery of four large boxes and eight small boxes has a total weight of 181 kg a delivery of two large boxes and three small boxes has a total weight of 77 kg how much does each type of box weigh

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.
