Incorrect. For any positive number a, the solution of $\displaystyle{\left|{X}\right|}={a}\usepackage{cmbright}\Huge\$ is $\displaystyle{X}={a}\usepackage{cmbright}\Huge\$ or $\displaystyle{X}=-{a}\usepackage{cmbright}\Huge\$ . Set up each equation and solve for the variable to find both values in the solution.
