One Step Inequalities Worksheet: Master Your Skills!
Table of Contents :
One-step inequalities are an essential part of algebra that help to understand the concept of solving problems with unknowns. Mastering these inequalities provides a solid foundation for more complex math concepts. In this blog post, we will delve into one-step inequalities, providing explanations, examples, and a worksheet to help you strengthen your skills.
What Are One-Step Inequalities? 🤔
One-step inequalities involve variables and constants that can be solved in a single step. These inequalities include symbols such as >, <, ≥, and ≤. For example:
- ( x + 3 > 5 )
- ( y - 4 < 10 )
In these examples, the goal is to isolate the variable (either ( x ) or ( y )) to find the solution set.
Understanding Inequality Symbols 🔍
Before we dive into solving, let’s clarify what each inequality symbol means:
| Symbol | Meaning |
|---|---|
> |
Greater than |
< |
Less than |
≥ |
Greater than or equal to |
≤ |
Less than or equal to |
Key Note:
Remember that when you multiply or divide both sides of an inequality by a negative number, the direction of the inequality changes.
Solving One-Step Inequalities 🚀
Let's break down the steps to solve one-step inequalities:
-
Identify the operation: Look for the operation being performed on the variable (addition, subtraction, multiplication, or division).
-
Perform the inverse operation: To isolate the variable, perform the opposite operation on both sides of the inequality.
-
Simplify: Ensure that the variable is on one side and the constant is on the other side.
-
Express the solution: Write your final answer, including the inequality symbol.
Example 1: Addition Inequality
Let’s solve the inequality ( x + 4 < 10 ):
- Step 1: Identify the operation: Addition
- Step 2: Perform the inverse operation: Subtract 4 from both sides
- Step 3: Simplify: ( x < 6 )
Final Answer: ( x < 6 )
Example 2: Subtraction Inequality
Consider the inequality ( y - 3 ≥ 2 ):
- Step 1: Identify the operation: Subtraction
- Step 2: Perform the inverse operation: Add 3 to both sides
- Step 3: Simplify: ( y ≥ 5 )
Final Answer: ( y ≥ 5 )
