Solving For B When A Is Two-Thirds And A Equals 36
Unraveling the Mystery: Solving for B
In this mathematical exploration, we embark on a journey to discover the value of B given the relationship between A and B and the specific value of A. The problem states that A is equal to two-thirds of B, and we know that A is equal to 36. Our mission is to use this information to determine the value of B. This type of problem falls under the umbrella of algebraic equations, where we use mathematical symbols and operations to represent relationships between quantities and solve for unknown values. Understanding how to solve such equations is a fundamental skill in mathematics, with applications spanning various fields, from science and engineering to finance and economics.
Setting Up the Equation: The Foundation of Our Solution
The first step in solving this problem is to translate the given information into a mathematical equation. We are told that "A is equal to two-thirds of B." This can be written mathematically as:
A = (2/3) * B
This equation forms the foundation of our solution. It expresses the relationship between A and B in a concise and symbolic form. We are also given that A = 36. This piece of information is crucial because it allows us to substitute the value of A into the equation, thereby creating an equation with only one unknown variable, B. This substitution is a key technique in solving algebraic equations.
Substituting A = 36 into the equation, we get:
36 = (2/3) * B
Now, we have a single equation with one unknown variable, B. Our next task is to isolate B on one side of the equation to determine its value. This involves using algebraic manipulations, which are essentially operations that we perform on both sides of the equation to maintain its balance while moving terms around.
Isolating B: Unveiling the Unknown
To isolate B, we need to get rid of the (2/3) factor that is multiplying it. The inverse operation of multiplication is division. However, instead of dividing both sides by (2/3), it is often easier to multiply both sides by the reciprocal of (2/3), which is (3/2). This is because multiplying by a fraction's reciprocal is the same as dividing by the fraction.
Multiplying both sides of the equation by (3/2), we get:
(3/2) * 36 = (3/2) * (2/3) * B
On the right side of the equation, the (3/2) and (2/3) cancel each other out, leaving us with just B. On the left side, we have (3/2) * 36. To simplify this, we can first divide 36 by 2, which gives us 18, and then multiply 18 by 3, which gives us 54. Therefore, the equation becomes:
54 = B
So, we have successfully isolated B and found its value. B is equal to 54. This is the solution to our problem. We have used the given information, set up an equation, and used algebraic manipulations to solve for the unknown variable. This process is a fundamental skill in mathematics and is used extensively in various applications.
Verification: Ensuring Accuracy
To ensure the accuracy of our solution, it is always a good practice to verify our answer. We can do this by substituting the value of B we found (B = 54) back into the original equation:
A = (2/3) * B
Substituting B = 54, we get:
A = (2/3) * 54
To simplify this, we can first divide 54 by 3, which gives us 18, and then multiply 18 by 2, which gives us 36. Therefore:
A = 36
This matches the given value of A, which was 36. This confirms that our solution for B is correct. Verification is a crucial step in problem-solving, as it helps us catch any potential errors and ensures that our answer is accurate.
The Significance of Algebraic Equations: A Broader Perspective
Algebraic equations are not just abstract mathematical concepts; they are powerful tools that help us model and solve real-world problems. The ability to translate real-world scenarios into mathematical equations and solve them is a valuable skill in various fields. For example, in physics, equations are used to describe the motion of objects, the behavior of light, and the interactions between particles. In engineering, equations are used to design structures, analyze circuits, and optimize processes. In finance, equations are used to calculate interest rates, model investments, and manage risk. In economics, equations are used to analyze supply and demand, predict market trends, and model economic growth.
The problem we solved here, while seemingly simple, illustrates the fundamental principles of algebra and equation solving. By understanding these principles, we can tackle more complex problems and apply them to a wide range of situations. The ability to manipulate equations, isolate variables, and solve for unknowns is a crucial skill for anyone pursuing a career in STEM fields (science, technology, engineering, and mathematics) or any field that involves quantitative analysis.
