You tried to solve the first inequality by subtracting 2, when you need to add 2 to both sides. Also, you tried to solve the second inequality by adding 8, when you need to subtract 8 from both sides. The solution to this compound inequality is $\displaystyle{x}\le{2}\usepackage{cmbright}\Huge\$ or $\displaystyle{x}>-{12}\usepackage{cmbright}\Huge\$ , which does not match the graph.
