To solve the first inequality, subtract 3 from both sides and then divide by $\displaystyle-{2}\usepackage{cmbright}\Huge\$ . This will reverse the inequality sign and give you $\displaystyle{b}\le{4}\usepackage{cmbright}\Huge\$ . To solve the second inequality, add 1 to both sides and then divide by $\displaystyle-{1}\usepackage{cmbright}\Huge\$ . This will reverse the inequality sign, giving you $\displaystyle{b}\ge{9}\usepackage{cmbright}\Huge\$ . The solution is all values of b that are either less than or equal to 4 or greater than or equal to 9.
