Answer 3

Solving the Problem in Two Steps

To solve the problem of comparing the lengths of two fairy tales, we can break it down into two steps:

Step 1: Define the Variables - Let's assume the length of the first fairy tale is represented by the variable x (in pages). - The length of the second fairy tale, which is 20 pages longer than the first, can be represented by the variable x + 20.

Step 2: Set Up the Equation and Solve - We can set up the equation by equating the total length of both fairy tales to 40 pages more than the length of the first fairy tale. - The equation can be represented as: x + (x + 20) = x + 40. - By solving this equation, we can find the value of x and then calculate the length of both fairy tales.

Solving the Equation

Let's solve the equation: - x + (x + 20) = x + 40 - Simplifying, we get: 2x + 20 = x + 40 - Subtracting x from both sides: x + 20 = 40 - Subtracting 20 from both sides: x = 20

Calculating the Length of Both Fairy Tales

Now that we have found the value of x: - The length of the first fairy tale (x) is 20 pages. - The length of the second fairy tale (x + 20) is 40 pages.

So, the first fairy tale is 20 pages long, and the second fairy tale is 40 pages long.
