You may have correctly decided to multiply both sides of the inequality by $\displaystyle-{3}\usepackage{cmbright}\Huge\$ to clear the fraction as your first step. However, you may have simplified $\displaystyle-{4}\cdot{\left(-{3}\right)}\usepackage{cmbright}\Huge\$ and gotten $\displaystyle-{12}\usepackage{cmbright}\Huge\$ , when it should be 12. The correct answer is $\displaystyle{d}<{2}\usepackage{cmbright}\Huge\$ .
