Solving One Step Inequalities

3
Example: x+3 < -5
Just like with equations, we need to first get rid of our constant, by bringing in zero pairs. Whatever you do to one side, you must do to the other.
This means that your answer any number that is less than or equal to 2
4
Multiple Choice
If the previous problem we got x < 2 as our answer. Is this a closed dot or open?
closed
open

Example 2
For this one, we want to rewrite it to where our variable is on the left because this will make it easier to graph.

Working with a negative variable
Just like equations, when we have a negative variable, we want to take care of it first
In this inequality, when we flip the variable, we will flip everything else including the inequality sign
Solve like normal
