So, let's embark on this mathematical journey to unravel the mystery of finding the whole number n and appreciate the underlying principles that govern the world of equations.

Understanding the Equation

The equation n + 72 = 158 is a simple yet fundamental algebraic equation. At its core, it states that when a certain whole number, n, is added to 72, the result is 158. Our objective is to isolate the variable n on one side of the equation to determine its value. To achieve this, we employ the principle of inverse operations. Inverse operations are mathematical operations that undo each other. In this case, the inverse operation of addition is subtraction. Therefore, to isolate n, we need to subtract 72 from both sides of the equation. This ensures that the equation remains balanced, adhering to the fundamental rule that what is done to one side must be done to the other. The concept of maintaining balance in an equation is paramount in algebra. It's like a seesaw; if you add or remove weight from one side, you must do the same on the other to keep it level. In the context of our equation, subtracting 72 from both sides preserves this balance, allowing us to isolate n without altering the fundamental relationship between the numbers. Understanding this principle is crucial for solving more complex equations in the future. Equations like n + 72 = 158 are the stepping stones to mastering algebra. They introduce the basic concepts of variables, constants, and inverse operations, which are essential tools in the mathematician's toolkit. So, let's proceed with the next step, armed with the knowledge of inverse operations and the importance of maintaining balance in equations.

Solving for n

To isolate n in the equation n + 72 = 158, we perform the inverse operation of addition, which is subtraction. We subtract 72 from both sides of the equation:

n + 72 - 72 = 158 - 72

This simplifies to:

n = 158 - 72

Now, we perform the subtraction:

n = 86

Therefore, the whole number n that satisfies the equation n + 72 = 158 is 86. This process demonstrates the power of inverse operations in solving algebraic equations. By applying the appropriate inverse operation, we can systematically isolate the variable and determine its value. The act of subtracting 72 from both sides of the equation is not just a mechanical step; it's a deliberate action based on the fundamental principles of algebra. It showcases the elegance and precision of mathematical operations in unraveling the unknown. The solution, n = 86, is not just a number; it's the answer to our mathematical puzzle. It's the missing piece that makes the equation whole. This process of solving for n highlights the importance of accuracy and attention to detail in mathematics. A single mistake in the subtraction could lead to an incorrect answer. Therefore, it's crucial to double-check our calculations and ensure that we have followed the steps correctly. Now that we have found the value of n, let's move on to verifying our solution and exploring its implications.

Verification

To ensure that our solution, n = 86, is correct, we substitute it back into the original equation:

86 + 72 = 158

Now, we perform the addition:

158 = 158

Since the left-hand side of the equation equals the right-hand side, our solution is verified. This step of verification is crucial in mathematics. It's the final checkpoint that confirms the accuracy of our solution. Substituting the value of n back into the original equation is like fitting the last piece of a jigsaw puzzle; it completes the picture and gives us the satisfaction of knowing that we have solved the problem correctly. The verification process not only confirms the correctness of our solution but also reinforces our understanding of the equation itself. It helps us see the relationship between the variable and the constants, solidifying our grasp of algebraic concepts. Moreover, verification is a valuable habit to cultivate in mathematics. It promotes accuracy and prevents careless errors from slipping through. In more complex problems, verification can be the difference between a correct and an incorrect answer. So, let's always make it a practice to verify our solutions, ensuring that our mathematical journey is both accurate and insightful. Now that we have verified our solution, let's proceed to discuss the answer and its significance.

Discussion of the Answer

The solution to the equation n + 72 = 158 is n = 86. This means that the whole number which, when added to 72, results in 158 is 86. The process of finding this solution involved understanding the concept of inverse operations and applying it to isolate the variable n. The answer, n = 86, is not just a numerical value; it's the result of a logical and systematic problem-solving approach. It demonstrates the power of algebra in unraveling mathematical puzzles and finding unknown quantities. This solution also highlights the importance of understanding the properties of whole numbers. Whole numbers, being non-negative integers, form the foundation of many mathematical concepts.
