You need to substitute the values $\displaystyle{x}={1}\usepackage{cmbright}\Huge\$ and $\displaystyle{y}={2}\usepackage{cmbright}\Huge\$ into the two inequalities. The values $\displaystyle{x}={1}\usepackage{cmbright}\Huge\$ and $\displaystyle{y}={2}\usepackage{cmbright}\Huge\$ is a solution to the first inequality, however it is not a solution to the second inequality. You may not have noticed the second inequality is a less than but not equal to.
