Introduction

Linear equations are a fundamental concept in mathematics, and solving them is a crucial skill for students to master. In this article, we will focus on solving a simple linear equation using a flowchart. We will use the equation $$2x + 5 = 17$$ as an example and guide you through the step-by-step process of completing the flowchart.

What is a Flowchart?

A flowchart is a visual representation of a process or a series of steps. It is a useful tool for solving problems, especially in mathematics. A flowchart typically consists of a series of boxes or shapes that represent different steps or decisions in the problem-solving process.

The Flowchart for Solving Linear Equations

The flowchart for solving linear equations is a simple and straightforward process. Here is the flowchart:

Step-by-Step Solution to the Equation $$2x + 5 = 17$$

Now that we have the flowchart, let's use it to solve the equation $$2x + 5 = 17$$.

Step 1: Is the Equation in the Form ax + b = c?

The equation $$2x + 5 = 17$$ is in the form ax + b = c, where a = 2, b = 5, and c = 17. Therefore, the answer to this question is Yes.

Step 2: Subtract b from Both Sides

Subtracting 5 from both sides of the equation gives us:

2x + 5 - 5 = 17 - 5

2x = 12

Step 3: Divide Both Sides by a

Dividing both sides of the equation by 2 gives us:

\frac{2x}{2} = \frac{12}{2}

x = 6

Step 4: The Value of x is the Solution

The value of x is 6, which is the solution to the equation $$2x + 5 = 17$$.

Conclusion

In this article, we have used a flowchart to solve the linear equation $$2x + 5 = 17$$. We have walked through the step-by-step process of completing the flowchart and have arrived at the solution, x = 6. This example demonstrates the usefulness of flowcharts in solving linear equations and provides a clear and concise guide for students to follow.
