**MathMate**, Tuesday, September 6, 2011 at 4:37pmYou would solve for one of the unknowns using the linear equation (x-y=1 => x=y+1)

and substitute into the quadratic equation, and solve for the only unknown, y.

(y+1)^2+y^2=5

y^2+y-2=0

y=1 or -2

Now substitute y=1 or -2 into the linear equation to get the corresponding values of x. This will complete the solution of two intersection points.
