A pot contained twice as much water as a bottle. The total amount of water in both the pot and the bottle was 5 l. What was the amount of the water in the bottle?
Jawaban:
5/3 liters of water
Penjelasan dengan langkah-langkah:
pot = 2 × bottle
pot + bottle = 5 liters
substitute pot with x and bottle with y.
x = 2y
x + y = 5
substitute x with 2y into the equation.
x + y = 5
2y + y = 5
3y = 5
y = 5/3 liters
the amount of water inside the bottle was 5/3 liters.
x = 2y
x = 2(5/3)
x = 10/3
the amount of water inside the pot was 10/3 liters.
