Answer 1

пусть х - кол-во бумаги в наборе.

получаем уравнение:

х - 5 - 6 = 14

х = 14 + 5 + 6

х = 25

Answer 2

Problem Analysis

To solve this problem, we need to determine the total number of sheets of paper in the set based on the information provided. We know that 5 sheets of red paper and 6 sheets of blue paper were used, leaving 14 sheets remaining. We need to find the initial number of sheets in the set.

Solution

Let's assume the initial number of sheets in the set is x.

We know that 5 sheets of red paper and 6 sheets of blue paper were used, so the total number of sheets used is 5 + 6 = 11.

We also know that there are 14 sheets remaining.

To find the initial number of sheets in the set, we can set up the following equation:

x - 11 = 14

To solve for x, we can add 11 to both sides of the equation:

x = 14 + 11

Simplifying the equation, we find:

x = 25

Therefore, the initial number of sheets in the set was 25.

Answer

The initial number of sheets in the set was 25.
