Answer 1

Пусть х учащихся было во втором классе, тогда в первом их было 3х. Составим и решим уравнение
х + 3х + 14 = 62
4х + 14 = 62
4х = 62 - 14
4х = 48
х = 48 : 4
х = 12
Значит, во втором  классе было 12 учащихся, а в первом - 12 · 3 = 36.
Ответ: 12 учащихся.

Answer 2

Problem Analysis

We are given that two classes went to a concert. The first class had three times as many students as the second class. When 14 more students joined the second class, the total number of students in both classes became 62. We need to find the number of students in the second class.

Solution

Let's assume the number of students in the second class is x. According to the given information, the number of students in the first class is 3 times the number of students in the second class, which is 3x.

When 14 more students joined the second class, the total number of students in both classes became 62. So, we can set up the following equation:

x + (3x + 14) = 62

Simplifying the equation:
