The inequality is
.
The above equation can be write into two equivalent inequalities:
\
.
Solve the inequality
to find w.
Subtract 9 from each side.
\

Divide each side by 2.
\

Solve the inequality
to find w.
Multiply each side by negative one, so flip the symbol.
\
Subtract 9 from each side.
\

Divide each side by 2.
\

So
or
