Subtract 2 from both sides, and then divide by $\displaystyle-{3}\usepackage{cmbright}\Huge\$ :

$\displaystyle-{3}{y}+{2}-{2}>{11}-{2}\usepackage{cmbright}\Huge\$ or $\displaystyle-{3}{y}>{9}\usepackage{cmbright}\Huge\$

$\displaystyle\frac{{-{3}{y}}}{{-{{3}}}}<\frac{{9}}{{-{{3}}}}\usepackage{cmbright}\Huge\$ or $\displaystyle{y}<-{3}\usepackage{cmbright}\Huge\$
