Solve For $w$.${ 8 + 2w = 10 }$Simplify Your Answer. $ W = $

Introduction

Linear equations are a fundamental concept in mathematics, and solving them is a crucial skill for students and professionals alike. In this article, we will focus on solving a simple linear equation, specifically the equation $8 + 2w = 10$. We will break down the solution step by step, using clear and concise language to ensure that readers understand the process.

What is a Linear Equation?

A linear equation is an equation in which the highest power of the variable(s) is 1. In other words, it is an equation that can be written in the form $ax + b = c$, where $a$, $b$, and $c$ are constants, and $x$ is the variable. Linear equations can be solved using various methods, including algebraic manipulation and graphical methods.

The Equation $8 + 2w = 10$

The equation $8 + 2w = 10$ is a simple linear equation that can be solved using basic algebraic manipulation. To solve for $w$, we need to isolate the variable $w$ on one side of the equation.

Step 1: Subtract 8 from Both Sides

The first step in solving the equation is to subtract 8 from both sides of the equation. This will help us to isolate the term containing the variable $w$.

${ 8 + 2w = 10 }$

Subtracting 8 from both sides gives us:

${ 2w = 10 - 8 }$

${ 2w = 2 }$

Step 2: Divide Both Sides by 2

Now that we have isolated the term containing the variable $w$, we can divide both sides of the equation by 2 to solve for $w$.

${ 2w = 2 }$

Dividing both sides by 2 gives us:

${ w = \frac{2}{2} }$

${ w = 1 }$

Conclusion

In this article, we solved the linear equation $8 + 2w = 10$ using basic algebraic manipulation. We broke down the solution into two steps, subtracting 8 from both sides and then dividing both sides by 2 to isolate the variable $w$. The final solution is $w = 1$. This equation is a simple example of a linear equation, and solving it requires a basic understanding of algebraic manipulation.
