#### Answer

$(2,2)$

#### Work Step by Step

Adding the two equations will eliminate y.
The resulting equation:
$2x=4\qquad/\div 2$
$x=2$
Back substitute into one of the initial equations:
$x-y=0$
$2-y=0\quad/+y$
$2=y.$
Solutions are ordered pairs (x,y):
$(2,2)$
Check graphically by graphing both lines in the same window and determining the intersection (see image).
