Solve the following inequation and graph the solution set on the number line: .
Step 1: Given inequations: .
Consider the inequality: .
Subtract to both sides of the inequality.
Step 2: Multiply to both sides of the inequality and change the sign of inequality.
Step 3: Solve the inequality , we need to consider that 2 different cases.
Case-1:
and
or, and
or,
Case-2:
and
or, and
or,
Thus, the solution set of the given inequality,
Step 4: Represent the solution set on the number line
Therefore, the solution set of and can be given by .
The solution set can be plotted on the number line as,
