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.
