\"\"\"\"\"\"

\

The original function is \"\"

\

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

\

First solve the case \"\".

\

Apply Addition property of equality: if a = b, then a - c = b - c.

\

\"\"                   (Add 2 from each side)

\

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

\

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

\

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

\

Next solve the case \"\".

\

\"\"                                   (Product of two same signs is positive)

\

\"\"                       (Add 2 from each side)

\

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

\

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

\

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

\

\"\"

\

First, draw a number line.

\

To graph the solutions set, mark the numbers –3 and 7 on number line.

\

\"numberline_absolute_pa325_p9\"\"\"

\

The solution set is \"\".
