The weight of the water container is 2.48 kg. If we pour 75% of water, the container with water weighs 0.98 kg. Find the weight of the empty container. How much water was originally in the container?

Correct answer:

x =  0.48 kg
y =  2 kg

Step-by-step explanation:

x+y = 2.48
x + 0.25y = 0.98

x+y = 2.48
x + 0.25•y = 0.98

x+y = 2.48
x+0.25y = 0.98

x = 12/25 = 0.48
y = 2
