So, let's embark on this mathematical journey and unravel the value of Q together.
Understanding the Equation Q - 12 = 89
At its core, the equation Q - 12 = 89 represents a fundamental algebraic relationship. The equation introduces us to the variable Q, which symbolizes an unknown quantity we aim to determine. The equation states that when 12 is subtracted from Q, the result is 89. To solve for Q, we must isolate it on one side of the equation. This involves performing operations that maintain the equality while systematically eliminating other terms. In essence, solving an equation is like a balancing act, where we strive to keep both sides equal while unraveling the unknown. This equation serves as a building block for more complex algebraic expressions and lays the groundwork for understanding advanced mathematical concepts. By mastering the techniques to solve such equations, we pave the way for tackling real-world problems and developing critical thinking skills.
Isolating the Variable Q
To isolate the variable Q in the equation Q - 12 = 89, we employ the principle of inverse operations. The term '-12' is attached to Q, indicating a subtraction operation. To undo this subtraction, we perform the inverse operation, which is addition. We add 12 to both sides of the equation, ensuring that the equality remains balanced. This step is crucial as it isolates Q on the left-hand side, bringing us closer to the solution. Mathematically, this can be represented as:
Q - 12 + 12 = 89 + 12
By adding 12 to both sides, we effectively eliminate the '-12' term on the left, leaving Q standing alone. This process exemplifies the power of inverse operations in algebra, allowing us to manipulate equations while preserving their fundamental truth.
Performing the Addition
After adding 12 to both sides of the equation, we arrive at a simplified expression: Q = 89 + 12. The next step involves performing the addition operation on the right-hand side of the equation. Adding 89 and 12 is a straightforward arithmetic calculation. The sum of 89 and 12 is 101. Therefore, we can rewrite the equation as:
Q = 101
This step is crucial in determining the value of Q. The addition operation combines the constants, leading us closer to the solution. Accuracy in this step is paramount, as an error in addition would lead to an incorrect value for Q.
The Solution Q = 101
After performing the addition, we arrive at the solution: Q = 101. This result signifies that the value of Q that satisfies the equation Q - 12 = 89 is 101. In other words, if we substitute 101 for Q in the original equation, the equation holds true. This solution provides a concrete answer to the problem posed by the equation. The value 101 represents the unknown quantity that, when decreased by 12, equals 89. This step is the culmination of our efforts to isolate Q and perform the necessary arithmetic operations. The solution Q = 101 is not just a numerical answer; it is a testament to the power of algebraic manipulation and problem-solving.
Verification of the Solution
To ensure the accuracy of our solution, it is essential to verify it. Verification involves substituting the value we found for Q back into the original equation and checking if the equation holds true. In our case, we substitute Q = 101 into the equation Q - 12 = 89. This yields:
101 - 12 = 89
Now, we perform the subtraction on the left-hand side:
89 = 89
The equation holds true, confirming that our solution Q = 101 is indeed correct. Verification is a crucial step in problem-solving as it provides confidence in the accuracy of the answer. It helps us catch any potential errors and reinforces our understanding of the equation and its solution. By verifying our solution, we complete the problem-solving process and solidify our grasp of the underlying mathematical principles.
Multiple Choice Options and the Correct Answer
In the context of multiple-choice questions, we are presented with several options, and our task is to identify the correct one. In the case of the equation Q - 12 = 89, the options provided are:
A. 102 B. 77 C. 101 D. 78
Based on our solution, we know that Q = 101. Comparing this with the options, we find that option C, 101, matches our solution. Therefore, option C is the correct answer. Multiple-choice questions test our ability to apply problem-solving skills and select the correct answer from a set of possibilities. Understanding the underlying concepts and performing the necessary calculations are crucial for success in such questions. In this case, by solving the equation and verifying the solution, we were able to confidently choose the correct option.
Common Mistakes to Avoid
When solving equations, it's easy to make mistakes if we're not careful. One common mistake is forgetting to perform the same operation on both sides of the equation. Remember, to keep the equation balanced, whatever you do on one side, you must also do on the other side. Another mistake is incorrectly applying inverse operations. For example, if the equation involves subtraction, we need to add to both sides, not subtract. Similarly, if the equation involves multiplication, we need to divide, not multiply. Additionally, arithmetic errors can lead to incorrect solutions. Double-checking your calculations, especially during addition and subtraction, can help prevent these mistakes. Keeping a clear and organized workspace can also minimize errors. When tackling complex equations, it's beneficial to break down the problem into smaller, manageable steps. This approach not only simplifies the problem but also makes it easier to identify and correct mistakes. By being mindful of these common pitfalls and adopting careful problem-solving strategies, we can enhance our accuracy and confidence in solving equations.
