Substitute 3 for x and 2 for y in each equation.

$\displaystyle{2}-{3}={1}\usepackage{cmbright}\Huge\$ $\displaystyle-{3}{\left({3}\right)}-{2}{\left({2}\right)}={5}\usepackage{cmbright}\Huge\$

$\displaystyle-{1}={1}\usepackage{cmbright}\Huge\$ False
$\displaystyle-{9}-{4}={5}\usepackage{cmbright}\Huge\$

$\displaystyle-{13}={5}\usepackage{cmbright}\Huge\$ False

Since the ordered pair does not make both equations true, it is not a solution to the system.

$\displaystyle{2}-{3}={1}\usepackage{cmbright}\Huge\$	$\displaystyle-{3}{\left({3}\right)}-{2}{\left({2}\right)}={5}\usepackage{cmbright}\Huge\$
$\displaystyle-{1}={1}\usepackage{cmbright}\Huge\$ False	$\displaystyle-{9}-{4}={5}\usepackage{cmbright}\Huge\$
	$\displaystyle-{13}={5}\usepackage{cmbright}\Huge\$ False
