x^2 - y^2 = 4

x + y = 2

This system can also be solved graphically. First, set each equation to the form y=

x^2 - y^2 = 4 y = sqrt(x^2 - 4)

x + y = 2 y = 2 - x

Here is the graph:

The point of intersection of the two graphs is (2, 0).

**Therefore, x = 2 and y = 0.**

If you do not have a graphing calculator, refer to the attached website. It will graph equations and calculate the point of intersection.
