Introduction

Linear equations are a fundamental concept in mathematics, and solving them is a crucial skill for students to master. In this article, we will explore how to solve linear equations using the distributive property, a key concept in algebra. We will also delve into the world of linear equations and discuss the importance of understanding this concept.

What is the Distributive Property?

The distributive property is a fundamental concept in algebra that allows us to expand expressions by multiplying each term inside the parentheses by a constant. In the context of linear equations, the distributive property is used to simplify expressions and solve for the variable.

Applying the Distributive Property to Linear Equations

Let's take a look at the given equation:

{ \begin{array}{l} 2(4x + 3) = 30 \\ \begin{array}{c} \text{First, use the} \\ \text{Distributive Property!} \end{array} \\ [?]x + [] = 30 \end{array} \}

To solve this equation, we need to apply the distributive property to the left-hand side of the equation. This means that we need to multiply each term inside the parentheses by 2.

Step 1: Multiply Each Term Inside the Parentheses by 2

Using the distributive property, we can rewrite the equation as:

{ \begin{array}{l} 8x + 6 = 30 \end{array} \}

Step 2: Simplify the Equation

Now that we have applied the distributive property, we can simplify the equation by combining like terms. In this case, we can subtract 6 from both sides of the equation to get:

{ \begin{array}{l} 8x = 24 \end{array} \}

Step 3: Solve for x

Finally, we can solve for x by dividing both sides of the equation by 8:

{ \begin{array}{l} x = 3 \end{array} \}

Introduction

In our previous article, we explored how to solve linear equations using the distributive property. In this article, we will answer some frequently asked questions about solving linear equations.

Q: What is the distributive property?

A: The distributive property is a fundamental concept in algebra that allows us to expand expressions by multiplying each term inside the parentheses by a constant.

Q: How do I apply the distributive property to linear equations?

A: To apply the distributive property to linear equations, you need to multiply each term inside the parentheses by a constant. For example, in the equation 2(4x + 3) = 30, you would multiply each term inside the parentheses by 2.

Q: What is the difference between a linear equation and a quadratic equation?

A: A linear equation is an equation in which the highest power of the variable is 1. For example, 2x + 3 = 5 is a linear equation. A quadratic equation, on the other hand, is an equation in which the highest power of the variable is 2. For example, x^2 + 4x + 4 = 0 is a quadratic equation.

Q: How do I solve a linear equation with fractions?

A: To solve a linear equation with fractions, you need to eliminate the fractions by multiplying both sides of the equation by the least common multiple (LCM) of the denominators.

Q: What is the least common multiple (LCM)?

A: The least common multiple (LCM) is the smallest multiple that is common to two or more numbers. For example, the LCM of 2 and 3 is 6.

Q: How do I solve a linear equation with decimals?

A: To solve a linear equation with decimals, you need to eliminate the decimals by multiplying both sides of the equation by a power of 10.

Q: What is the difference between a linear equation and a system of linear equations?

A: A linear equation is an equation in which the highest power of the variable is 1. A system of linear equations, on the other hand, is a set of two or more linear equations that are solved simultaneously.

Q: How do I solve a system of linear equations?

A: To solve a system of linear equations, you need to use methods such as substitution or elimination to find the values of the variables.

Q: What are some common mistakes to avoid when solving linear equations?
