Question

На трьох вулицях селища разом 208 будинків, на першій і другій вулиці разом 135 будинків, а на другій і третій 159 будинків. Скільки будинків на кожній вулиці

Answer 1

1) 208-135=73(дом.)-3 улица
2)208-159=49(дом)-1 улица
3)208-(73+49)=86(дом)-2 улица

Answer 2

Calculating the Number of Houses on Each Street

To solve this problem, we can use a system of equations. Let's denote the number of houses on the first street as x, the number of houses on the second street as y, and the number of houses on the third street as z.

We are given the following information: 1. On three streets together, there are 208 houses. 2. On the first and second streets together, there are 135 houses. 3. On the second and third streets together, there are 159 houses.

We can express this information as a system of equations: 1. x + y + z = 208 (equation 1) 2. x + y = 135 (equation 2) 3. y + z = 159 (equation 3)

Solving the System of Equations

We can solve this system of equations to find the values of x, y, and z.

First, let's solve equations 2 and 3 simultaneously to find the value of y: - From equation 2: x + y = 135 - From equation 3: y + z = 159

Subtracting equation 2 from equation 3, we get: z - x = 24 (equation 4)

Now, we can add equations 2 and 4 to find the value of z: - (z - x) + (x + y) = 135 + 159 - z + y = 294 - z = 294 - y (equation 5)

Next, we can substitute the value of z from equation 5 into equation 1: - x + y + (294 - y) = 208 - x + 294 = 208 - x = 208 - 294 - x = -86

This gives us a negative value for x, which is not possible in this context. It seems there might be an error in the given information or the question. If you have additional information or if there's a specific way you'd like to proceed, please let me know!
