Answer 2

Solution:

Let's solve this problem step by step.

Let's assume the amount of honey in the first barrel is x kg and in the second barrel is y kg.

According to the given information, we have the following equations: 1. x + y = 49 (total amount of honey in both barrels) 2. (x - 7) - (y - 2) = 0 (the remaining amount of honey in both barrels after taking out 7 kg from the first barrel and 2 kg from the second barrel)

We can solve these equations to find the initial amounts of honey in each barrel.

Calculation:

From the first equation, we can express y in terms of x: y = 49 - x

Substitute y in the second equation: (x - 7) - ((49 - x) - 2) = 0 x - 7 - 49 + x + 2 = 0 2x - 54 = 0 2x = 54 x = 27

Now, we can find y: y = 49 - 27 y = 22

Answer:

So, initially, there were 27 kg of honey in the first barrel and 22 kg of honey in the second barrel.

Therefore, the initial amounts of honey in the first and second barrels were 27 kg and 22 kg respectively.
