Solving One- and Two-Step Equations
A Quick Review
2
Linear Equations
An equation that contains one variable
Used to solve for an unknown value that makes the equation true.
3
Solutions to Linear Equations
When you solve a linear equation, you are trying to find the unknown value (represented by the variable).
You must keep both sides of the equation balanced by performing equal operations to both sides of the equal sign.
4
Solving Linear Equations
To solve an equation, you must undo the equation by using inverse operations.
The order of the operations you perform is important.

Solving Two-Step Equations
These equations are called "two-step" because the equation involves more than one operation.
The equation must be solved by undoing the order of the operations.
10
Inverse Order of Operations
To solve an equation with more than one operation, remember to work PEMDAS backwards!

Inverse PEMDAS
This equation contains multiplication (8b) and addition.
To solve this equation, we undo the equation by working PEMDAS backwards and doing inverse operations.
REMEMBER, when you solve an equation, anything you do to one side, you must do to the other side. It must stay balanced
