Если Маше и Пете вместе 18 лет. Петя младше Маши в 2 раза. Пусть x лет будет Пете , тогда маше 2x. составляем уравнение 
2x+x=18
3x=18
x=18/3
x=6 лет.
6 лет - Пете.

Answer 3

Calculating the Ages of Masha and Petya

To calculate the ages of Masha and Petya, we can use the information provided in the question. According to the question, Masha and Petya have been together for 18 years, and Masha is twice as old as Petya.

Let's denote Masha's age as M and Petya's age as P. We can create the following equations based on the given information:

1. M + P = 18 (Masha and Petya have been together for 18 years) 2. M = 2P (Masha is twice as old as Petya)

We can solve this system of equations to find the ages of Masha and Petya.

Solving the Equations

Substituting the value of M from the second equation into the first equation: 2P + P = 18 3P = 18 P = 6

Now that we have found Petya's age, we can find Masha's age using the second equation: M = 2 * 6 M = 12

Conclusion

Based on the given information, Masha is 12 years old and Petya is 6 years old.
