5 Simple Linear Equations to Solve Now

Introduction to Linear Equations

Linear equations are a fundamental concept in mathematics, and they are used to describe relationships between variables. A linear equation is an equation in which the highest power of the variable(s) is 1. In this article, we will focus on simple linear equations and provide examples for you to solve.

What is a Linear Equation?

A linear equation is an equation that can be written in the form of:

ax + b = c

where:

• x is the variable
• a is the coefficient of the variable
• b is the constant term
• c is the constant term on the other side of the equation

How to Solve Linear Equations

To solve a linear equation, you need to isolate the variable (x) on one side of the equation. Here are the steps:

1. Add or subtract the same value to both sides of the equation to get rid of the constant term (b).
2. Multiply or divide both sides of the equation by the same value to get rid of the coefficient (a).

📝 Note: Make sure to follow the order of operations (PEMDAS) when solving linear equations.

5 Simple Linear Equations to Solve

Here are five simple linear equations for you to solve:

1. 2x + 5 = 11

To solve this equation, subtract 5 from both sides:

2x = 11 - 5 2x = 6

Then, divide both sides by 2:

x = ⁶⁄₂ x = 3

1. x - 3 = 7

To solve this equation, add 3 to both sides:

x = 7 + 3 x = 10

1. 4x = 24

To solve this equation, divide both sides by 4:

x = ²⁴⁄₄ x = 6

1. x + 2 = 9

To solve this equation, subtract 2 from both sides:

x = 9 - 2 x = 7

1. 3x - 2 = 14

To solve this equation, add 2 to both sides:

3x = 14 + 2 3x = 16

Then, divide both sides by 3:

x = ¹⁶⁄₃ x = 5.33

Tips and Tricks

Here are some tips and tricks to help you solve linear equations:

• Always follow the order of operations (PEMDAS) when solving linear equations.
• Use inverse operations to isolate the variable. For example, if the equation has a +, use - to get rid of it.
• Check your answer by plugging it back into the original equation.

🤔 Note: Make sure to check your units when solving linear equations with units.

Linear equations are an essential part of mathematics, and they are used in many real-world applications. By practicing and solving simple linear equations, you can improve your problem-solving skills and build a strong foundation in mathematics.
