You can put this solution on YOUR website! pair of linear equations in two variables with one solution.
To graph, put in slope intercept form, which they both are
y=mx+b
m for the first is slope and -2. The y-intercept is 3. The graph goes through (0, 3) and has a slope of -2, 1 to the right and down 2 or 1 to the left and up 2.
m for the second has slope 1 (x is 1x). The y-intercept is -3.
The graph goes through (0, -3) with slope 1, right 1 up 1, left 1 down 1.
