Step 1 :
\The rational inequality is .
State the exclude values, those are the values for which the denominator is zero.
\The exclude value of the inequality is 3.
\Step 2 :
\Solve the related equation .
Solution of related equation .
Step 3 :
\Draw the vertical lines at the exclude values and at the solution to separate the number line into intervals.
\Step 4 :
\Now test sample values in each interval to determine whether the values in the interval satisfy the inequality.
\Test interval | \![]() | \

Step 5 :
\Since the original inequality contains a symbol, exclude it into set of solutions at
.
Since the above statement is true, is a solution of inequality.
Conclude that the inequality is satisfied for all - values in
and
.
Solution of the inequality is
.
