Introduction

Simplifying algebraic expressions is a fundamental concept in mathematics, and it's essential to understand how to do it correctly. In this article, we will focus on simplifying a linear equation, which is a type of algebraic expression that consists of variables and constants. We will use the given expression $5m + 3n - 2m + n = 1$ as an example to demonstrate the steps involved in simplifying a linear equation.

Understanding the Expression

Before we start simplifying the expression, let's take a closer look at it. The given expression is $5m + 3n - 2m + n = 1$ . This expression consists of four terms: $5m$ , $3n$ , $-2m$ , and $n$ . The first two terms are positive, while the last two terms are negative. The expression is also equal to 1, which means that the sum of the four terms is equal to 1.

Combining Like Terms

One of the key concepts in simplifying algebraic expressions is combining like terms. Like terms are terms that have the same variable or variables with the same exponent. In this case, we have two like terms: $5m$ and $-2m$ . These two terms have the same variable, which is $m$ , and the same exponent, which is 1. We can combine these two terms by adding their coefficients.

# Combine like terms
m_coefficient = 5 - 2
print(m_coefficient)

The output of the above code is 3, which means that the coefficient of the combined term is 3. Therefore, the expression can be simplified as follows:

$3m + 3n + n = 1$

Simplifying the Expression Further

Now that we have combined the like terms, we can simplify the expression further by combining the remaining like terms. In this case, we have two like terms: $3n$ and $n$ . These two terms have the same variable, which is $n$ , and the same exponent, which is 1. We can combine these two terms by adding their coefficients.

# Combine like terms
n_coefficient = 3 + 1
print(n_coefficient)

The output of the above code is 4, which means that the coefficient of the combined term is 4. Therefore, the expression can be simplified as follows:

$3m + 4n = 1$

Conclusion

Simplifying algebraic expressions is an essential skill in mathematics, and it's crucial to understand how to do it correctly. In this article, we have demonstrated the steps involved in simplifying a linear equation, which is a type of algebraic expression that consists of variables and constants. We have used the given expression $5m + 3n - 2m + n = 1$ as an example to demonstrate the steps involved in simplifying a linear equation.

Q&A

Q: What is a linear equation?

A: A linear equation is a type of algebraic expression that consists of variables and constants. It is an equation in which the highest power of the variable is 1.

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

Q: How do I simplify a linear equation?

A: To simplify a linear equation, you need to combine like terms and isolate the variable. Like terms are terms that have the same variable or variables with the same exponent. You can combine like terms by adding or subtracting their coefficients.

Q: What is the purpose of simplifying algebraic expressions?

A: The purpose of simplifying algebraic expressions is to make them easier to work with and to understand the underlying relationships between the variables and constants.

Q: How do I know if an equation is linear or not?

A: To determine if an equation is linear or not, you need to look at the highest power of the variable. If the highest power of the variable is 1, then the equation is linear. If the highest power of the variable is greater than 1, then the equation is not linear.

Q: Can I simplify an equation with more than one variable?

A: Yes, you can simplify an equation with more than one variable. However, you need to make sure that you are combining like terms correctly.

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

A: A linear equation is a single equation that consists of variables and constants, while a system of linear equations 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: Can I use a calculator to simplify algebraic expressions?
