\

The original function is $\"\"$

\

Write $\"\"$ as $\"\"$ or $\"\"$ $\"\"$

\

First solve the case $\"\"$ .

\

$\"\"$ (Subtract 7 from each side)

\

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

\

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

\

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

\

Apply Division proparty of inequality: If a = b than $\"\"$

\

$\"\"$ (Divide each side by 3)

\

$\"\"$ (Cancel commen terms)

\

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

\

Next solve the casev . $\"\"$

\

$\"\"$ $\"\"$ (Subtract 7 from each side)

\

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

\

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

\

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

\

Apply Division proparty of inequality: If a = b than $\"\"$

\

$\"\"$ $\"\"$ (Divide each side by 3)

\

$\"\"$ $\"\"$ (Cancel commen terms)

\

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

\

To graph the solutions set, first draw a number line.

\

Draw a heavy line between-4 and -0.6

\

Since -4 and -0.6 are not included in the solution set, draw a solid at -4 and -0.6.

\

$\"absolute$

\

$\"\"$

\

The solution set is $\"\"$ .
