To solve the first inequality, add 5 to both sides and then divide by $\displaystyle-{3}\usepackage{cmbright}\Huge\$ . This will reverse the inequality sign and give you $\displaystyle{b}>{1}\usepackage{cmbright}\Huge\$ . To solve the second inequality, add 4 to both sides to get $\displaystyle{b}\le{4}\usepackage{cmbright}\Huge\$ . The solution is all values of b greater than 1 or less than or equal to 4. Therefore, b could be any number and the solution is all real numbers.
