Question

Ребята, кому не сложно,помогите. Решите задачу с помощью уравнения: За 4 одинаковых блокнота и 2 одинаковых альбома заплатили 112 р. Один альбом дороже одного блокнота на 8 р. Сколько стоит один блокнот? Помогите прошу вас, умоляю. Я ваш ответ отмечу, как "лучшим" обещаю!!! Помогите;(

Answer 1

Пусть 1 блокнот - х рублей. Тогда 1 альбом - х+8. Составим и решим уравнение:
4х+2(х+8)=112
4х+2х+16=112
6х=96
х=96:6
х=16
Итак, 1 блокнот - 16 рублей

Answer 2

Problem Analysis

To solve this problem, we can set up a system of equations based on the given information. Let's assume the cost of one notebook is x rubles. Since one album is more expensive than one notebook by 8 rubles, the cost of one album will be x + 8 rubles.

System of Equations

We can now set up the following system of equations based on the given information:

Equation 1: 4x + 2(x + 8) = 112

Solving the System of Equations

Let's solve the system of equations to find the value of x, which represents the cost of one notebook.

4x + 2(x + 8) = 112

Simplifying the equation:

4x + 2x + 16 = 112

Combining like terms:

6x + 16 = 112

Subtracting 16 from both sides:

6x = 96

Dividing both sides by 6:

x = 16

Answer

The cost of one notebook is 16 rubles.
