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

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
