One-Step Equations
What are One-Step Equations?
One-step equations are the simplest type of algebraic equations. They require only one operation (addition, subtraction, multiplication, or division) to solve for the variable.
Examples of One-Step Equations
The goal when solving an equation is to isolate the variable (get it by itself on one side of the equation).
The Balance Method
When solving equations, think of the equals sign as a balance. Whatever you do to one side of the equation, you must do to the other side to keep the equation balanced.
Key Principles
Addition and Subtraction
To isolate a variable with addition or subtraction, perform the opposite operation on both sides.
Multiplication and Division
To isolate a variable with multiplication or division, perform the opposite operation on both sides.
Solving One-Step Equations
Addition Equation: x + 5 = 12
To isolate x, subtract 5 from both sides.
Subtraction Equation: x - 3 = 7
To isolate x, add 3 to both sides.
Multiplication Equation: 3x = 15
To isolate x, divide both sides by 3.
Division Equation: x/4 = 5
To isolate x, multiply both sides by 4.
