\"\"

\

The inequality is \"\".

\

Solve the inequality.

\

\"\"                         (Original inequality)

\

\"\"             (Add \"\" to each side)

\

\"\"                                 (Apply additive inverse property: \"\")

\

The graph of the solution set on a number line diagram.\"Graph

\

A circle means that this point is not included in the solution set.

\

\"\"

\

Check solution for \"\"-value.

\

Case(i): \"\"

\

\"\"                         (Original inequality)

\

\"\"                       (Substitute \"\")

\

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

\

Therefore, \"\" is true inequality.

\

Case(ii): \"\"

\

\"\"                        (Original inequality)

\

\"\"                      (Substitute \"\")

\

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

\

Therefore, \"\" is false inequality.

\

\"\"

\

The solution set of the inequality is \"\".
