Answer 2

Problem Solution:

To solve the problem, we need to determine the number of pencils in the box before and after taking out 5 pencils.

Let's assume the number of pencils in the box before taking out 5 pencils is x.

According to the problem, when 5 pencils are taken out, there are 4 pencils left in the box.

So, we can set up the equation: x - 5 = 4.

To find the value of x, we can solve this equation:

x - 5 = 4

Adding 5 to both sides of the equation:

x = 4 + 5

Simplifying:

x = 9

Therefore, there were originally 9 pencils in the box.

Number of Pencils in Two Such Boxes:

If we have two boxes with the same number of pencils, we can simply multiply the number of pencils in one box by 2.

Since there were 9 pencils in one box, the number of pencils in two such boxes would be:

9 x 2 = 18 pencils.

So, there would be 18 pencils in two such boxes.
