Expressions, Inequalitys, and Equations
Equations
Two Step Equations
To subtract you must: keep, change, flip and follow adding rules
-
To add you must: if a sign is the same add , if the sign is different then subtract values.
One Step Equations
-
-
One step equations require variables and has you undoing division, multiplication, and addition/subtraction.
Multi-Step Equations
-
You also need to divide the number on the outside of the parentheses, then subtract/add the constant and Voila! You have your answer!
-
Inequalitys
One Step Inequalitys
-
Graphs are required however when you finish an inequality you must not only graph but if you had to divide you must flip the sign
-
Two Step Inequalitys
-
-
Make sure to flip the inequality sign when finished multiplying/dividing otherwise the problem will be wrong
