Introduction

In mathematics, solving equations is a fundamental concept that helps us find the missing values in various mathematical expressions. In this article, we will explore how to use a given equation to find the missing value in a tabular representation. We will use a simple equation and a tabular representation to demonstrate the concept.

The Equation

The given equation is $x = 5y$ . This equation represents a linear relationship between the variables $x$ and $y$ . We will use this equation to find the missing value in the tabular representation.

The Tabular Representation

The tabular representation is shown below:

$x$	10	20	30	40
$y$	5	10	15	?

Finding the Missing Value

To find the missing value, we need to substitute the values of $x$ and $y$ from the tabular representation into the equation $x = 5y$ . We will start by substituting the values of $x$ and $y$ from the first row of the tabular representation.

For the first row, $x = 10$ and $y = 5$ . Substituting these values into the equation, we get:

10 = 5(5)

Simplifying the equation, we get:

10 = 25

This equation is not true, so we need to find the correct value of $y$ for $x = 10$ . Let's try to find the value of $y$ that satisfies the equation.

x = 5y

10 = 5y

Dividing both sides of the equation by 5, we get:

y = 2

So, the correct value of $y$ for $x = 10$ is 2.

Finding the Missing Value in the Tabular Representation

Now that we have found the correct value of $y$ for $x = 10$ , we can substitute this value into the tabular representation to find the missing value.

$x$	10	20	30	40
$y$	2	10	15	?

We can see that the value of $y$ for $x = 20$ is 10, which is already given in the tabular representation. So, we need to find the value of $y$ for $x = 30$ and $x = 40$ .

For $x = 30$ , we can substitute the value of $x$ into the equation:

30 = 5y

Dividing both sides of the equation by 5, we get:

y = 6

So, the correct value of $y$ for $x = 30$ is 6.

For $x = 40$ , we can substitute the value of $x$ into the equation:

40 = 5y

Dividing both sides of the equation by 5, we get:

y = 8

So, the correct value of $y$ for $x = 40$ is 8.

Conclusion

In this article, we used a simple equation and a tabular representation to find the missing value. We substituted the values of $x$ and $y$ from the tabular representation into the equation and solved for the missing value. We found that the correct values of $y$ for $x = 10$ , $x = 30$ , and $x = 40$ are 2, 6, and 8, respectively.

The complete tabular representation is shown below:

$x$	10	20	30	40
$y$	2	10	6	8

Discussion

The concept of solving equations is a fundamental concept in mathematics that helps us find the missing values in various mathematical expressions. In this article, we used a simple equation and a tabular representation to demonstrate the concept. We found that the correct values of $y$ for $x = 10$ , $x = 30$ , and $x = 40$ are 2, 6, and 8, respectively.

Introduction

In our previous article, we explored how to use a given equation to find the missing value in a tabular representation. In this article, we will provide a Q&A guide to help you understand the concept of solving equations and how to apply it to various mathematical problems.

Q: What is an equation?

A: An equation is a statement that two mathematical expressions are equal. It is a way of expressing a relationship between two or more variables.

Q: What is a linear equation?

A: A linear equation is an equation in which the highest power of the variable is 1. It is a simple equation that can be solved using basic algebraic operations.

Q: How do I solve a linear equation?

A: To solve a linear equation, you need to isolate the variable on one side of the equation. You can do this by adding, subtracting, multiplying, or dividing both sides of the equation by the same value.

Q: What is a tabular representation?

A: A tabular representation is a way of displaying data in a table format. It is often used to show the relationship between two or more variables.
