Correct. First simplify each inequality so that the absolute value expression stands alone on one side, if necessary. For $\displaystyle{\left|{X}\right|}\ge{a}\usepackage{cmbright}\Huge\$ the solution is $\displaystyle{X}\ge{a}\usepackage{cmbright}\Huge\$ or $\displaystyle{X}\le-{a}\usepackage{cmbright}\Huge\$ . For $\displaystyle{\left|{X}\right|}\le{a}\usepackage{cmbright}\Huge\$ the solution is $\displaystyle-{a}\le{X}\le{a}\usepackage{cmbright}\Huge\$ .
