$\"addition$ $\"\"$

The inequality is $\"\"$

Apply addition property of inequality: Add 5 to each side.

$\"\"$ $\"\"$

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

$\"\"$ (Add: 7 + 5 = 12)

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

Graph the solution set on a number line.

$\"number$

Note: A Graph dot means that this point is included in the solution set. $\"\"$

Check:

To check, substitute 12, a number greater than or equal to 12 in $\"\"$ .

$\"\"$ (Substitute t = 12)

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

The inequality is true. $\"\"$

The inequality solution is $\"\"$ .
