One bag contains 2 times more flour than another. After 25 kg of flour was taken from the first bag, and 7 kg from the second, the flour in both bags became equal. How many kg of flour were in each bag originally?

Let x be the quantity in the second bag, then 2x is the quantity in the first bag.
So, let’s make the equation:
2x – 25 = x – 7
2x – x = – 7 + 25
x = 18
18 kg. – in the first bag
18 * 2 = 26 kg. – in the second bag
