Add 25 to both sides of the first inequality to get $\displaystyle{9}{j}\le{54}\usepackage{cmbright}\Huge\$ . Then divide by 9 to get $\displaystyle{j}\le{6}\usepackage{cmbright}\Huge\$ . Subtract 18 from both sides of the second inequality to get $\displaystyle{6}{j}>{60}\usepackage{cmbright}\Huge\$ . Then divide by 6 to get $\displaystyle{j}>{10}\usepackage{cmbright}\Huge\$ . Since the graphs of $\displaystyle{j}\le{6}\usepackage{cmbright}\Huge\$ and $\displaystyle{j}>{10}\usepackage{cmbright}\Huge\$ have no overlap, there is no solution.
