Question

В вазе было груш в 2раза меньше,чем яблок.Когда в вазу положили еще 4груши,то их стало столько же,сколько и яблок.сколько яблок было а вазе?

Answer 1

Если принять количество яблок за x, то груш было в 2 раза меньше, то есть x/2. Когда добавили ещё 4 груши (то есть x/2 + 4), груш стало столько же, сколько яблок, то есть x. Таким образом, составляется уравнение:

x = x/2 + 4

откуда следует, что x = 8

Answer 2

Problem Analysis

We are given that there were twice as many apples as pears in a vase. When 4 pears were added to the vase, the number of pears became equal to the number of apples. We need to determine the number of apples that were initially in the vase.

Solution

Let's assume the initial number of pears in the vase is x. According to the problem, the number of apples in the vase is twice the number of pears, so the initial number of apples is 2x.

When 4 pears are added to the vase, the number of pears becomes x + 4. At the same time, the number of apples remains the same, which is 2x.

Since the number of pears and apples becomes equal, we can set up the following equation:

x + 4 = 2x

Now, let's solve this equation to find the value of x.

x + 4 = 2x

Subtracting x from both sides:

4 = x

Therefore, the initial number of pears in the vase is 4.

Since the number of apples is twice the number of pears, the initial number of apples in the vase is 2 * 4 = 8.

So, there were 8 apples initially in the vase.

Answer

The initial number of apples in the vase was 8.
