\"\"

\

From the SSS inequality theorem , \"\".

\

\"\"               (SSS inequality)

\

\"\"      (Substitute \"\")

\

\"\"             (Add 100 to each side)

\

\"\"                     (Subtract 5x from each side)

\

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

\

Since the measure of any angle is always greater than zero.

\

\"\"

\

\"\"                     (Add 100 to each side)

\

\"\"                     (Divide each side by 8)

\

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

\

The two inequalities can be written as the compound inequality \"\"\"\"

\

The inequality to the possible values of x  is \"\".
