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 focus on solving a specific linear equation, 14n+6p−8n=18p14n + 6p - 8n = 18p, for the variable nn. We will break down the solution step by step, using algebraic manipulations to isolate the variable nn.

Understanding the Equation

Before we dive into the solution, let's take a closer look at the equation:

14n+6p−8n=18p14n + 6p - 8n = 18p

This equation is a linear equation in two variables, nn and pp. The goal is to solve for nn in terms of pp.

Step 1: Combine Like Terms

The first step in solving the equation is to combine like terms. In this case, we have two terms with the variable nn: 14n14n and −8n-8n. We can combine these terms by adding their coefficients:

14n−8n=6n14n - 8n = 6n

So, the equation becomes:

6n+6p=18p6n + 6p = 18p

Step 2: Isolate the Variable nn

Now that we have combined like terms, we can isolate the variable nn by subtracting 6p6p from both sides of the equation:

6n=18p−6p6n = 18p - 6p

Simplifying the right-hand side, we get:

6n=12p6n = 12p

Step 3: Solve for nn

Finally, we can solve for nn by dividing both sides of the equation by 66:

n=12p6n = \frac{12p}{6}

Simplifying the fraction, we get:

n=2pn = 2p

Conclusion

In this article, we solved the linear equation 14n+6p−8n=18p14n + 6p - 8n = 18p for the variable nn. By combining like terms, isolating the variable nn, and solving for nn, we arrived at the solution:

n=2pn = 2p

This solution shows that the variable nn is directly proportional to the variable pp. The constant of proportionality is 22.

Answer Key

Based on the solution, the correct answer is:

B. n=2pn = 2p

Introduction

In our previous article, we solved the linear equation 14n+6p−8n=18p14n + 6p - 8n = 18p for the variable nn. We received many questions from readers who were struggling to understand the solution. In this article, we will address some of the most common questions and provide additional guidance on solving linear equations.

Q: What is a linear equation?

A: 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+by=cax + by = c

where aa, bb, and cc are constants, and xx and yy are variables.

Q: How do I know if an equation is linear?

A: To determine if an equation is linear, look for the following characteristics:

  • The highest power of the variable(s) is 1.
  • The equation can be written in the form ax+by=cax + by = c.
  • The equation does not contain any exponents or roots.

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(s) is 1, while a quadratic equation is an equation in which the highest power of the variable(s) is 2. For example:

  • Linear equation: 2x+3y=52x + 3y = 5
  • Quadratic equation: x2+4x+4=0x^2 + 4x + 4 = 0

Q: How do I solve a linear equation?

A: To solve a linear equation, follow these steps:

  1. Combine like terms.
  2. Isolate the variable(s) by adding, subtracting, multiplying, or dividing both sides of the equation by the same value.
  3. Solve for the variable(s) by performing the necessary operations.

Q: What is the order of operations?

A: The order of operations is a set of rules that tells you which operations to perform first when solving an equation. The order of operations is:

  1. Parentheses: Evaluate expressions inside parentheses first.
  2. Exponents: Evaluate any exponential expressions next.
  3. Multiplication and Division: Evaluate any multiplication and division operations from left to right.
  4. Addition and Subtraction: Finally, evaluate any addition and subtraction operations from left to right.

Q: How do I use the order of operations to solve an equation?

A: To use the order of operations to solve an equation, follow these steps:

  1. Evaluate any expressions inside parentheses.
  2. Evaluate any exponential expressions.
  3. Evaluate any multiplication and division operations from left to right.
  4. Evaluate any addition and subtraction operations from left to right.

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

A: A linear equation is a single equation with one or more variables, while a system of linear equations is a set of two or more linear equations with the same variables. For example:

  • Linear equation: 2x+3y=52x + 3y = 5
  • System of linear equations: 2x+3y=52x + 3y = 5 and x−2y=−3x - 2y = -3
