Answer 3

Problem Analysis

Kolya multiplied a number by 3 and then subtracted 8 from the product, resulting in 50. We need to determine the original number that Kolya had in mind.

Solution

Let's assume the number Kolya had in mind is represented by the variable 'x'. According to the problem statement, we can set up the following equation:

3x - 8 = 50

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

Solving the Equation

Adding 8 to both sides of the equation, we get:

3x = 50 + 8 3x = 58

Dividing both sides of the equation by 3, we find:

x = 58 / 3

Using long division, we can calculate the value of 'x':

  19
-----
3 | 58
  - 57
   ---
    1

Therefore, the value of 'x' is 19.

Answer

Kolya had the number 19 in mind.
