Answer 1

30-5=25 домов на второй улице
30+25=55 домов на третьей улице

Answer 2

Task Solution

To solve this problem, we can use algebraic equations to represent the given information and then solve for the unknowns.

Let's denote: - the number of houses on the first street as x - the number of houses on the second street as x - 5 (since it's five houses less than the first street) - the number of houses on the third street as 1 (as there's only one house on the third street)

We can then form the following equations based on the given information: 1. x + (x - 5) + 1 = 30 (the total number of houses on the first and second streets is 30) 2. x + (x - 5) = 30 - 1 (the total number of houses on the first and second streets, excluding the third street, is 30 - 1)

Let's solve these equations to find the values of x and x - 5.

Solution Steps

1. Equation 1: x + (x - 5) + 1 = 30 2. Equation 2: x + (x - 5) = 30 - 1 3. Solve for x 4. Calculate the number of houses on the second street (x - 5) 5. Calculate the total number of houses on the third street

Let's proceed with the solution.
