Answer 2

Solution:

Let's solve this problem step by step.

1. Set up the equations: - Let's assume the number of cars Vasiliy has is represented by V and the number of cars Petya has is represented by P. - We know that Vasiliy has 20 more cars than Petya, so we can express this as: V = P + 20. - We also know that together they have 50 cars, so we can express this as: V + P = 50.

2. Solve the equations: - Using the first equation V = P + 20, we can substitute the value of V in the second equation. - Substituting V = P + 20 into V + P = 50, we get (P + 20) + P = 50. - Simplifying, we get 2P + 20 = 50. - Solving for P, we get 2P = 30 and therefore P = 15. - Substituting the value of P back into the equation V = P + 20, we get V = 15 + 20 which equals V = 35.

3. Conclusion: - Therefore, Petya has 15 cars and Vasiliy has 35 cars.

Final Answer:

Petya has 15 cars and Vasiliy has 35 cars.
