Question

За 3 корочки хлеба и 2 кружки молока надо заплатить 20 монет. Сколько стоит 1 корочка хлеба, если она дешевле одной кружки молока на 5 монет?

Answer 1

3х+2*(х+5)=20
3х+2х+10=20
5х+10=20
5х=20-10
5х=10

х=10:5
х=2

вот и всё уравнение  

Answer 2

пусть кор хлеба стоит х монет , тогда
молоко стоит х+5 монет

 смоставим уравнение

3х+ 2х+10=20 
5х=10

х= 2

2+5=7

Problem Analysis

We are given the information that 3 loaves of bread and 2 cups of milk cost a total of 20 coins. We need to determine the cost of one loaf of bread if it is cheaper than one cup of milk by 5 coins.

Solution

Let's assume the cost of one loaf of bread is x coins. Since the loaf of bread is cheaper than one cup of milk by 5 coins, the cost of one cup of milk would be (x + 5) coins.

According to the given information, 3 loaves of bread and 2 cups of milk cost a total of 20 coins. We can set up the following equation to represent this information:

3x + 2(x + 5) = 20

Simplifying the equation:

3x + 2x + 10 = 20 5x + 10 = 20 5x = 10 x = 2

Therefore, the cost of one loaf of bread is 2 coins.

Answer

The cost of one loaf of bread is 2 coins.

Explanation

To solve this problem, we set up an equation based on the given information and solved for the cost of one loaf of bread. The equation was 3x + 2(x + 5) = 20, where x represents the cost of one loaf of bread. By simplifying the equation, we found that x = 2, indicating that one loaf of bread costs 2 coins.
