H2: Understanding the Equation: -4 = 3/w
Before diving into the solution, let's take a moment to understand the equation -4 = 3/w. This equation is a simple algebraic equation that involves a fraction. The left side of the equation is the constant -4, while the right side is a fraction where 3 is the numerator and w is the denominator. Our goal is to isolate w on one side of the equation to determine its value. The key to solving this equation lies in recognizing the relationship between w and the fraction 3/w. The variable w is in the denominator, which means it is dividing the constant 3. To isolate w, we need to perform the inverse operation, which is multiplication. However, we must also be mindful of the properties of equality, which state that we can perform the same operation on both sides of the equation without changing its balance. This principle is fundamental to solving algebraic equations and ensures that our manipulations maintain the integrity of the solution. Visualizing the equation as a balance scale can be helpful. The left side represents one weight (-4), and the right side represents another weight (3/w). To maintain the balance, any operation we perform on one side must be mirrored on the other side. This conceptual understanding will guide us as we proceed with the steps to solve for w. Furthermore, it's crucial to remember that w cannot be equal to zero because division by zero is undefined in mathematics. This constraint is important to keep in mind as we manipulate the equation and interpret our solution. Understanding the nuances of the equation sets the stage for a clear and effective solution process. By grasping the roles of the constants, the variable, and the fractional representation, we can approach the problem with confidence and avoid common errors.
H2: Step-by-Step Solution to Isolate w
Now, let's embark on the step-by-step solution to isolate w in the equation -4 = 3/w. This involves a series of algebraic manipulations that adhere to the fundamental principles of equality. Our primary goal is to get w by itself on one side of the equation. The first step in solving for w is to eliminate the fraction. We can achieve this by multiplying both sides of the equation by w. This operation is based on the principle that multiplying a fraction by its denominator cancels out the denominator. So, we multiply both sides of the equation by w: w * (-4) = w * (3/w). This simplifies to -4w = 3. Now, w is no longer in the denominator, but it is being multiplied by -4. To isolate w, we need to perform the inverse operation of multiplication, which is division. We divide both sides of the equation by -4: (-4w) / -4 = 3 / -4. This simplifies to w = -3/4. Therefore, the solution to the equation -4 = 3/w is w = -3/4. Each step in this solution process is crucial and serves a specific purpose. Multiplying both sides by w clears the fraction, and dividing both sides by -4 isolates w. These operations are carefully chosen to maintain the balance of the equation while moving us closer to the solution. It's also important to note that we have arrived at a solution that does not violate any mathematical rules. Specifically, w = -3/4 is not equal to zero, so our solution is valid. By carefully following these steps and understanding the underlying principles, you can confidently solve similar equations and further develop your algebraic skills. This methodical approach to problem-solving is a valuable asset in mathematics and many other fields.
H2: Verification: Ensuring the Correctness of the Solution
After arriving at a solution, it's crucial to perform a verification step. This step ensures the correctness of our solution and helps us catch any potential errors we might have made during the solution process. To verify our solution, we substitute w = -3/4 back into the original equation, -4 = 3/w, and check if both sides of the equation are equal. Substituting w = -3/4 into the equation gives us: -4 = 3 / (-3/4). To divide by a fraction, we multiply by its reciprocal. The reciprocal of -3/4 is -4/3. So, the equation becomes: -4 = 3 * (-4/3). Now, we simplify the right side of the equation: -4 = -12/3. Further simplification gives us: -4 = -4. Since both sides of the equation are equal, our solution w = -3/4 is verified. This verification step is not just a formality; it's a critical part of the problem-solving process. It gives us confidence in our solution and ensures that we have not made any algebraic errors. By substituting the solution back into the original equation, we are essentially retracing our steps and confirming that each operation we performed was valid. Furthermore, the verification step reinforces our understanding of the equation and the relationships between the variables and constants. It highlights the importance of maintaining the balance of the equation throughout the solution process. In summary, the verification step is an essential component of mathematical problem-solving. It not only validates our solution but also enhances our understanding and reinforces good mathematical practices. By consistently verifying our solutions, we can build confidence in our abilities and minimize the risk of errors.
