Expressions and Equations
One-step equations
Multiplication
Model
Create a key/legend, Set up the problem, Isolate your variable (x1), What you do to one side you must do to the other side Identify your answer when you have separated your variables and have separated your constants.
Algorithm
he goal is to get your variable to have an coefficient (number in front) of 1.
Determine what you can divide by to divide the coefficient to 1.
What you do to one side you do to the other.
Division
Model
Make sure to create a key Make sure to divide your variable/unknown appropriately Figure out how many groups you need to get a whole x (1x) Fill in all missing parts of x to get a whole x (1x)
Algorithm
Multiply both sides by what you are dividing by
How to check answers
Addition/Subtractions
Model
Create a key/legend, Set up the problem, Find zero pairs by adding or subtraction, Identify your answer when your variable is isolated.
Algorithm
The goal is to get your variable, identify how the constant is connected to the unknown, Add or subtract to get to zero.
two step equations and inequalities
Method 1
identify the opposite action/operation
Identify the reverse order of the step
Method 2
Method 2
Circle the variable term and do everything besides that
