Answer 2

Этот текст точно правильно написан?Перевод все равно как-то ,,нормальным" не получается. Джон, двенадцать лет, в три раза старше, как и его брат. Как старый Джон будет, когда он в два раза старше своего брата?

Answer 3

To solve this problem, let's break it down step by step.

Step 1: Define the variables

Let's assign variables to the ages of John and his brother: - Let J represent John's current age. - Let B represent his brother's current age.

Step 2: Translate the problem into equations

According to the problem, John is currently twelve years old and is three times as old as his brother. This can be expressed as: - J = 12 - J = 3B

Step 3: Solve the equations

We can substitute the value of J from the first equation into the second equation: - 12 = 3B

Solving for B, we divide both sides of the equation by 3: - B = 12 / 3 - B = 4

So, John's brother is currently four years old.

Step 4: Determine John's age when he is twice as old as his brother

To find out how old John will be when he is twice as old as his brother, we need to find the age at which J = 2B.

Substituting the value of B into the equation J = 2B: - J = 2 * 4 - J = 8

Therefore, John will be eight years old when he is twice as old as his brother.
