In the realm of mathematics, problem-solving often involves translating word problems into algebraic equations, the problem presents a classic scenario where the difference between a fraction of a number and a constant is equal to another fraction of the same number. This article delves into the step-by-step process of solving this problem, emphasizing the core concepts of algebraic manipulation and equation solving. Our focus keyword is on finding a specific number by translating the word problem into an algebraic equation. We aim to provide a comprehensive explanation that caters to both students and math enthusiasts alike, making the solution accessible and understandable. Understanding the fundamental principles of algebra is crucial for tackling such problems, and we'll be highlighting these principles throughout our explanation. The problem at hand requires us to identify a number that satisfies a particular condition involving fractions and differences. Let's begin by dissecting the problem statement and converting it into a mathematical equation.

The heart of solving mathematical word problems lies in the ability to translate the given information into a concise and accurate equation. This involves identifying the unknowns, assigning variables, and representing the relationships between these variables using mathematical symbols. In this specific problem, the unknown is the number we're trying to find, which we'll denote as 'x'. The phrase "the difference of 110\frac{1}{10} of a number and 30" can be translated to x10−30\frac{x}{10} - 30, where x10\frac{x}{10} represents one-tenth of the number x, and the subtraction of 30 represents the difference. Similarly, "15\frac{1}{5} of the number" is expressed as x5\frac{x}{5}. The problem states that these two expressions are equal, which leads us to the equation x10−30=x5\frac{x}{10} - 30 = \frac{x}{5}. This equation forms the backbone of our solution, and solving it will lead us to the answer. The process of translating words into equations is a fundamental skill in algebra and is essential for problem-solving. By carefully dissecting the problem statement and identifying the key components, we can construct an equation that accurately represents the given information. This step is crucial for success in solving mathematical word problems. In the following sections, we will demonstrate how to solve this equation using various algebraic techniques.

Now that we have our equation, x10−30=x5\frac{x}{10} - 30 = \frac{x}{5}, we can embark on the journey of solving it. The primary goal here is to isolate the variable 'x' on one side of the equation. To achieve this, we'll employ a series of algebraic manipulations. The first step involves eliminating the fractions. We can do this by multiplying both sides of the equation by the least common multiple (LCM) of the denominators, which in this case is 10. Multiplying both sides by 10 gives us: 10∗(x10−30)=10∗(x5)10 * (\frac{x}{10} - 30) = 10 * (\frac{x}{5}). This simplifies to x−300=2xx - 300 = 2x. Next, we want to gather all the terms involving 'x' on one side of the equation. We can subtract 'x' from both sides, resulting in −300=x-300 = x. Thus, we find that the number we're looking for is -300. This step-by-step approach highlights the importance of maintaining balance in an equation. Any operation performed on one side must also be performed on the other side to preserve equality. This principle is the cornerstone of equation solving. By carefully applying algebraic techniques, we can systematically isolate the variable and arrive at the solution. In the next section, we'll verify this solution to ensure its correctness.

After obtaining a solution, it's crucial to verify its accuracy. This involves substituting the solution back into the original equation and checking if it satisfies the equation. In our case, we found that x = -300. Let's substitute this value into the original equation: x10−30=x5\frac{x}{10} - 30 = \frac{x}{5}. Substituting x = -300, we get −30010−30=−3005\frac{-300}{10} - 30 = \frac{-300}{5}. Simplifying the left side, we have -30 - 30 = -60. Simplifying the right side, we have -60. Since both sides are equal (-60 = -60), our solution x = -300 is correct. This verification process is an essential step in problem-solving. It helps us catch any errors we might have made during the solution process and ensures that our final answer is accurate. By substituting the solution back into the original equation, we can confirm that it satisfies the given conditions. This practice reinforces the understanding of the problem and builds confidence in the solution. In the subsequent sections, we'll summarize the entire solution process and discuss the key takeaways from this problem.
