$\"\"$

$\"\"$ (Additive inverse property: $\"\"$ )

$\"\"$ (Additive identity property: $\"\"$ )

$\"\"$ (Subtract: $\"\"$ ) $\"number$

Note: A circle means that this point is not included in the solution set. $\"\"$

Check:

To check, substitute a number less than -2, in $\"\"$ .

$\"\"$ (Substitute a = $\"\"$ 2)

$\"\"$ (Sustract: $\"\"$ )

The inequality is true. $\"\"$

The inequality solution is $\"\"$ .
