Introduction
Mathematical equations can be complex and require a series of steps to solve. In this article, we will guide you through the process of solving a mathematical equation by dragging each step and justification to the correct location in a table. We will also provide an example equation to demonstrate the process.
Understanding the Equation
Before we begin, it's essential to understand the equation we are trying to solve. Let's consider the following equation:
2x + 5 = 11
Our goal is to isolate the variable x and find its value.
Step 1: Write Down the Equation
The first step in solving the equation is to write it down. This may seem obvious, but it's essential to have a clear understanding of the equation before we begin.
| Step | Justification |
|---|---|
| 1. Write down the equation | To have a clear understanding of the equation |
Step 2: Identify the Variable
The next step is to identify the variable in the equation. In this case, the variable is x.
| Step | Justification |
|---|---|
| 2. Identify the variable | To isolate the variable x |
Step 3: Isolate the Variable
To isolate the variable x, we need to get rid of the constant term on the same side of the equation as the variable. In this case, we can subtract 5 from both sides of the equation.
| Step | Justification |
|---|---|
| 3. Subtract 5 from both sides | To isolate the variable x |
Step 4: Simplify the Equation
After subtracting 5 from both sides, we get:
2x = 6
| Step | Justification |
|---|---|
| 4. Simplify the equation | To make the equation easier to solve |
Step 5: Divide Both Sides by 2
To isolate the variable x, we need to divide both sides of the equation by 2.
| Step | Justification |
|---|---|
| 5. Divide both sides by 2 | To isolate the variable x |
Step 6: Solve for x
After dividing both sides by 2, we get:
x = 3
| Step | Justification |
|---|---|
| 6. Solve for x | To find the value of the variable x |
Conclusion
In this article, we have guided you through the process of solving a mathematical equation by dragging each step and justification to the correct location in a table. We have also provided an example equation to demonstrate the process. By following these steps, you can solve mathematical equations with ease.
Example Equation
Let's consider another example equation:
x - 2 = 7
We can follow the same steps to solve this equation:
| Step | Justification |
|---|---|
| 1. Write down the equation | To have a clear understanding of the equation |
| 2. Identify the variable | To isolate the variable x |
| 3. Add 2 to both sides | To isolate the variable x |
| 4. Simplify the equation | To make the equation easier to solve |
| 5. Solve for x | To find the value of the variable x |
By following these steps, we can solve the equation x - 2 = 7 and find the value of the variable x.

Introduction
Solving mathematical equations can be a challenging task, but with the right guidance, it can become a breeze. In this article, we will answer some of the most frequently asked questions about solving mathematical equations.
Q: What is the first step in solving a mathematical equation?
A: The first step in solving a mathematical equation is to write down the equation. This may seem obvious, but it's essential to have a clear understanding of the equation before we begin.
Q: How do I identify the variable in a mathematical equation?
A: To identify the variable in a mathematical equation, look for the letter or symbol that is being solved for. In most cases, the variable is the letter or symbol that is being isolated.
Q: What is the difference between an equation and an expression?
A: An equation is a statement that says two things are equal, while an expression is a group of numbers and/or variables that are combined using mathematical operations. For example, 2x + 5 is an expression, while 2x + 5 = 11 is an equation.
Q: How do I simplify a mathematical equation?
A: To simplify a mathematical equation, combine like terms and eliminate any unnecessary operations. For example, 2x + 2x + 5 can be simplified to 4x + 5.
Q: What is the inverse operation?
A: The inverse operation is a mathematical operation that undoes another operation. For example, addition and subtraction are inverse operations, as are multiplication and division.
Q: How do I use inverse operations to solve a mathematical equation?
A: To use inverse operations to solve a mathematical equation, identify the operation that is being performed on the variable and then perform the inverse operation to isolate the variable. For example, if the equation is 2x + 5 = 11, we can subtract 5 from both sides to get 2x = 6, and then divide both sides by 2 to get x = 3.
Q: What is the order of operations?
A: The order of operations is a set of rules that dictate the order in which mathematical operations should be performed. The order of operations is:
- Parentheses: Evaluate any expressions inside parentheses first.
- Exponents: Evaluate any exponential expressions next.
- Multiplication and Division: Evaluate any multiplication and division operations from left to right.
- Addition and Subtraction: Finally, evaluate any addition and subtraction operations from left to right.
Q: How do I check my answer?
A: To check your answer, plug it back into the original equation and see if it is true. For example, if we solved the equation 2x + 5 = 11 and got x = 3, we can plug x = 3 back into the original equation to get 2(3) + 5 = 11, which is true.
Conclusion
Solving mathematical equations can be a challenging task, but with the right guidance, it can become a breeze. By following the steps outlined in this article and answering the frequently asked questions, you can become proficient in solving mathematical equations and tackle even the most complex problems with ease.
