The Mysterious Number: A Mathematical Puzzle

Are you ready to put your mathematical skills to the test? In this article, we will delve into a fascinating mathematical puzzle that requires a combination of arithmetic operations to arrive at a surprising solution. The puzzle states: "If you multiply me by 7, subtract 2, and then divide by 6, you get 9." The question is, what number am I?

Understanding the Puzzle

To solve this puzzle, we need to break it down into smaller steps and analyze each operation individually. Let's start by understanding the given operations:

Multiply the number by 7
Subtract 2 from the result
Divide the result by 6

Our goal is to find a number that satisfies all these operations and results in 9.

The Algebraic Approach

One way to approach this puzzle is to use algebraic equations. Let's represent the unknown number as 'x'. We can then write an equation based on the given operations:

(7x - 2) / 6 = 9

To solve for 'x', we can start by multiplying both sides of the equation by 6 to eliminate the fraction:

7x - 2 = 54

Next, we can add 2 to both sides of the equation to isolate the term with 'x':

7x = 56

Finally, we can divide both sides of the equation by 7 to solve for 'x':

x = 8

The Intuitive Approach

While the algebraic approach provides a clear and systematic solution, we can also try to solve this puzzle using intuition and logical reasoning. Let's think about the given operations:

Multiplying a number by 7 will result in a larger number.
Subtracting 2 from the result will reduce the number further.
Dividing the result by 6 will further reduce the number.

Given that the final result is 9, we can work backwards to find the original number. Let's start by multiplying 9 by 6 to get the result before the division:

9 × 6 = 54

Next, we can add 2 to 54 to get the result before the subtraction:

54 + 2 = 56

Finally, we can divide 56 by 7 to get the original number:

56 ÷ 7 = 8

Conclusion

In this article, we have explored a fascinating mathematical puzzle that requires a combination of arithmetic operations to arrive at a surprising solution. Using both algebraic and intuitive approaches, we have found that the original number is 8. This puzzle highlights the importance of logical reasoning and problem-solving skills in mathematics.
