(2, 0) is a solution for the system because it is a solution to both inequalities. However, $\displaystyle{\left(-{1},-{2}\right)}\usepackage{cmbright}\Huge\$ is not a solution for the system. It is not a solution to either of the inequalities. If you substitute these numbers into the inequalities and simplify, you will get $\displaystyle-{2}<-{2}\usepackage{cmbright}\Huge\$ and $\displaystyle{0}>{0}\usepackage{cmbright}\Huge\$ , which are both false statements.
