One-Step Equations Worksheet: Practice & Solutions Guide
Table of Contents :
One-step equations are fundamental concepts in algebra that form the basis for more complex mathematical problems. In this guide, we will delve into the details of one-step equations, provide practice problems, and offer solutions to help you master this essential skill. Let's break down this important topic in a comprehensive manner.
What are One-Step Equations? 🤔
A one-step equation is an algebraic equation that can be solved in a single step. These equations often involve addition, subtraction, multiplication, or division, allowing students to isolate the variable efficiently. For example, consider the equation:
- ( x + 5 = 12 )
In this case, the goal is to isolate ( x ) by performing the inverse operation (subtracting 5).
Importance of One-Step Equations
Mastering one-step equations is crucial for several reasons:
- Foundation for Algebra: They serve as the building blocks for more advanced algebra concepts.
- Problem-Solving Skills: Solving these equations enhances critical thinking and analytical skills.
- Real-World Applications: One-step equations are used in various practical scenarios, such as budgeting and measuring.
Types of One-Step Equations 📚
There are four primary types of one-step equations based on the operations involved:
- Addition Equations: ( x + a = b )
- Subtraction Equations: ( x - a = b )
- Multiplication Equations: ( ax = b )
- Division Equations: ( \frac{x}{a} = b )

Practice Problems 📝
To help solidify your understanding of one-step equations, here are some practice problems. Try solving them on your own before checking the solutions!
- Solve for ( x ): ( x + 7 = 15 )
- Solve for ( x ): ( x - 4 = 10 )
- Solve for ( x ): ( 5x = 25 )
- Solve for ( x ): ( \frac{x}{3} = 12 )
Important Note:
"Always perform the inverse operation to isolate the variable effectively!"
Solutions to Practice Problems 📊
Now that you've had a chance to try solving the equations, let's review the solutions:
-
( x + 7 = 15 )
Solution: Subtract 7 from both sides:
( x = 15 - 7 )
( x = 8 ) -
( x - 4 = 10 )
Solution: Add 4 to both sides:
( x = 10 + 4 )
( x = 14 ) -
( 5x = 25 )
Solution: Divide both sides by 5:
( x = \frac{25}{5} )
( x = 5 ) -
( \frac{x}{3} = 12 )
Solution: Multiply both sides by 3:
( x = 12 \times 3 )
( x = 36 )
