Introduction

In mathematics, equations are a fundamental concept that helps us understand and solve various problems. One of the most common types of equations is the addition equation, which involves finding the value of a variable by adding or subtracting numbers. In this article, we will focus on solving the addition equation $\frac{8}{7} = m + \frac{2}{7}$, where $m$ is the variable we need to find.

Understanding the Equation

The given equation is $\frac{8}{7} = m + \frac{2}{7}$. To solve for $m$, we need to isolate the variable on one side of the equation. In this case, we can start by subtracting $\frac{2}{7}$ from both sides of the equation.

Subtracting $\frac{2}{7}$ from Both Sides

When we subtract $\frac{2}{7}$ from both sides of the equation, we get:

$$\frac{8}{7} - \frac{2}{7} = m + \frac{2}{7} - \frac{2}{7}$$

Simplifying the left-hand side of the equation, we get:

$$\frac{6}{7} = m$$

Solving for $m$

Now that we have isolated the variable $m$ on the left-hand side of the equation, we can solve for its value. Since $\frac{6}{7} = m$, we can conclude that the value of $m$ is $\frac{6}{7}$.

Example and Solution

Let's consider an example to illustrate the concept. Suppose we have the equation $\frac{9}{4} = x + \frac{3}{4}$, where $x$ is the variable we need to find. To solve for $x$, we can follow the same steps as before:

$$\frac{9}{4} - \frac{3}{4} = x + \frac{3}{4} - \frac{3}{4}$$

Simplifying the left-hand side of the equation, we get:

$$\frac{6}{4} = x$$

Since $\frac{6}{4}$ can be simplified to $\frac{3}{2}$, we can conclude that the value of $x$ is $\frac{3}{2}$.

Conclusion

In conclusion, solving the addition equation $\frac{8}{7} = m + \frac{2}{7}$ involves isolating the variable $m$ on one side of the equation. By subtracting $\frac{2}{7}$ from both sides of the equation, we can simplify the left-hand side and solve for the value of $m$. This concept can be applied to various types of equations, and it is an essential skill to master in mathematics.
