**Solving Linear Equations with Tape Diagrams**

Introduction

Tape diagrams are a visual representation of mathematical equations, providing a powerful tool for solving linear equations. In this article, we will explore how to use tape diagrams to solve linear equations, with a focus on the equation $4x + 24 = 60$ . We will break down the steps involved in solving this equation using a tape diagram and provide a clear, step-by-step solution.

Understanding Tape Diagrams

A tape diagram is a graphical representation of an equation, where the variables and constants are represented by different sections of a tape. The tape is divided into sections, with each section representing a different part of the equation. The length of each section corresponds to the value of the variable or constant it represents.

Representing the Equation

Alice's tape diagram represents the equation $4x + 24 = 60$ . To represent this equation using a tape diagram, we need to divide the tape into sections that correspond to the variables and constants in the equation.

The first section represents the variable $x$ , with a length of $4$ units.
The second section represents the constant $24$ , with a length of $24$ units.
The third section represents the constant $60$ , with a length of $60$ units.

Solving the Equation

To solve the equation $4x + 24 = 60$ , we need to isolate the variable $x$ . We can do this by subtracting $24$ from both sides of the equation, which will give us $4x = 36$ . Then, we can divide both sides of the equation by $4$ , which will give us $x = 9$ .

Using a Tape Diagram to Solve the Equation

Now that we have understood the equation and the steps involved in solving it, let's use a tape diagram to solve the equation.

First, we draw a tape with three sections, representing the variable $x$ , the constant $24$ , and the constant $60$ .
We then draw a line to represent the equation $4x + 24 = 60$ .
Next, we subtract $24$ from both sides of the equation by moving the second section to the right of the line.
This gives us $4x = 36$ .
We then divide both sides of the equation by $4$ by moving the first section to the right of the line.
This gives us $x = 9$ .

Conclusion

In this article, we have explored how to use tape diagrams to solve linear equations. We have used a tape diagram to represent the equation $4x + 24 = 60$ and solved the equation by subtracting $24$ from both sides and then dividing both sides by $4$ . The solution to the equation is $x = 9$ . We hope that this article has provided a clear and step-by-step solution to the equation and has helped you to understand how to use tape diagrams to solve linear equations.
