Answer 1

На Парковой - х домов, тогда на Молодежной -( х+3) дома
х+х+3=19
2х=19-3
2х=16
х=16:2
х=8 (домов)- на Парковой;
8+3=11(домов)- на Молодежной.

Answer 2

Solving the Equation for the Number of Restored Houses on Each Street

To solve the equation, let's denote the number of houses restored on Parkovaya Street as x and the number of houses restored on Molodyozhnaya Street as y. We are given that on Parkovaya Street, 3 houses were restored less than on Molodyozhnaya Street. This can be represented by the equation:

x = y - 3

We also know that the total number of restored houses on Parkovaya Street is 12. This can be represented by the equation:

x = 12

Similarly, the total number of restored houses on Molodyozhnaya Street is 15. This can be represented by the equation:

y = 15

Calculating the Number of Restored Houses on Each Street

Using the equation x = 12, we find that the number of houses restored on Parkovaya Street is 12.

Using the equation y = 15, we find that the number of houses restored on Molodyozhnaya Street is 15.

Therefore, the number of houses restored on Parkovaya Street is 12, and the number of houses restored on Molodyozhnaya Street is 15.
