Answer 3

Problem Analysis

To solve this problem, we need to find the number that Kolya had in mind. We are given that Kolya multiplied the number by three, subtracted seven from the product, and obtained a result of 50. Let's represent the unknown number as 'x' and set up the equation based on the given information.

Solution

Let's set up the equation based on the given information: 3x - 7 = 50

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

Adding 7 to both sides of the equation: 3x = 50 + 7 3x = 57

Dividing both sides of the equation by 3: x = 57 / 3 x = 19

Therefore, the number that Kolya had in mind is 19.

Conclusion

Kolya had the number 19 in mind.
