Hi ELCAN, let's solve this problem about container mass together.
Problem Setup
Let x be the mass of the empty container, and y be the mass of the water when the container is completely full.
We are given that when the container is half full, its mass increases by 60 percent to reach the full mass of 2 kilograms. So, 2 equals 1.6 times the mass when half full.
Calculating 2 divided by 1.6 gives us 1.25. So, the mass when half full is 1.25 kilograms.
Now we have a system of two equations: x plus y equals 2 and x plus 0.5y equals 1.25.
