Eddie's moving company moved 3 boxes out of Mrs. Diaz's house. The box labeled "kitchen" was 4 times heavier than the box labeled Bedroom. The box labeled "library" was 14 times heavier than the box marked "Bedroom". If the combined weight of the boxes was 817 pounds, how much did the box labeled "kitchen" weigh

Respuesta :

k - Kitchen
b - Bedroom
l - Library

k = 4b
l = 14b
k   + b +  l    = 817 pounds
4b + b +14b = 817 pounds
19b = 817 lbs
b = 817/19 pounds
b = 43 pounds

Since k = 4b
k = 4 * 43 pounds
k = 172 pounds
