Answer 2

Problem Analysis

We are given that Julia bought a book for 38 rubles and had 20 rubles less than the cost of the book remaining. She used the remaining money to buy pens of the same price. We need to determine the cost of the pen.

Solution

Let's assume the cost of the pen is x rubles.

According to the given information, Julia had 20 rubles less than the cost of the book remaining after buying it for 38 rubles. This can be represented by the equation:

38 + x = x - 20

Simplifying the equation, we get:

38 + 20 = x - x

58 = 0

The equation 58 = 0 is not possible, which means there is no solution to this problem. It seems there might be an error in the given information or the problem itself.
