X - цена книги.

x+3x=272
4x=272
x=68 р стоимость одной книги.

68*3 = 204 р цена второй книги

Answer 2

Solution:

Let's solve the problem step by step.

1. Let's assume the price of one book is x rubles and the price of the other book is y rubles.

2. We are given that the total cost of both books is 272 rubles, so we can write the equation: - x + y = 272.

3. We are also given that the price of one book is one-third the price of the other book, so we can write the equation: - x = (1/3)y.

4. Now, we can use these two equations to solve for the values of x and y.

Substituting the value of x from the second equation into the first equation: - (1/3)y + y = 272 - (4/3)y = 272 - y = (3/4) * 272 - y = 204

Substituting the value of y back into the second equation: - x = (1/3) * 204 - x = 68

Answer:

So, the price of each book is 68 rubles and 204 rubles respectively.
