Answer to Problem 90RE
In order to solve an inequality, the following things can be done.
• Add the same number to each side of the inequality.
• Subtract the same number from each side .
• Multiply or divide each side by the same number and if multiplied or divided each side by a negative number, then the inequality symbol must be reversed.
The inequality can be solved as follows:
The solution using interval notation is
The shaded region shows solution of the given inequality on the graph below .
