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

The inequality is $\"\"$ .

Apply division property of inequality: Divide each side by 12.

$\"\"$

$\"\"$ (Cancel commen terms)

$\"\"$ (Divide: $\"\"$ ) $\"\"$

Check:

To check, substitute three different values for b into the original inequality: $\"\"$ , a number less than $\"\"$ , and greater than $\"\"$ .

Let three values are $\"\"$ .

If $\"\"$ then $\"\"$ (This is false)

If $\"\"$ then $\"\"$ (This is true). $\"\"$

The inequality solution set is $\"\"$ .
