Bag

Nelly found an interesting point. An empty bag weighs 4 kg less than the full. An empty bag is five times easier than a full. How many kg weigh things in this bag?

Correct answer:

x =  4 kg

Step-by-step explanation:


t+4=t+x
t = (t+x)/5

x = 4
4t-x = 0

Pivot: Row 1 ↔ Row 2
4t-x = 0
x = 4


x = 4/1 = 4
t = 0+x/4 = 0+4/4 = 1

t = 1
x = 4
