\

The original function is $\"\"$

\

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

\

First solve the case $\"\"$ .

\

$\"\"$ (Add 4 TO each side)

\

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

\

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

\

$\"\"$ (Add: $\"\"$ ) $\"\"$

\

Next solve the case $\"\"$ .

\

$\"\"$ (ADD 4 TO each side)

\

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

\

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

\

$\"\"$ (Add: $\"\"$ ) $\"\"$

\

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

\

Draw a heavy line between 7 and 1. Since 7 and 1 are not included in the solution set draw a circle at 7 and 1.
