Question

Carl is boarding a plane. He has 2 checked bags of equal weight and a backpack that weighs 4kg. The total weight of Carl's baggage is 35kg.

Write an equation to determine the weight, w, of each of Carl's checked bags.

Answer 1

Let a checked bag = x
Since they are of the same weight
The two checked bags = x+x=2x
Another backpack that weighs 4kg
Total baggage =35
:- 2x + 4 = 35
2x = 35-4
2x = 31

The two checked bag weighs 31
Therefore the weight of one =15.5kg
