Luca and William are playing a video game and they have scored a total of 20,000 points. Luca scored 8,000 more points than William. If you let $\displaystyle{l}=\usepackage{cmbright}\Huge\$ the number of points that Luca scored, and $\displaystyle{w}=\usepackage{cmbright}\Huge\$ the number of points that William scored, then the problem can be represented by the system:

$\displaystyle{l}+{w}={20},{000}\usepackage{cmbright}\Huge\$ and $\displaystyle{l}={w}+{8},{000}\usepackage{cmbright}\Huge\$

Graph the system. How many points did each boy score?
