I'm to find the points of intersection, if any, of the graphs of the equations:
x^2 + y^2 = 25 and 2x+y=10
I solved for y for both equations and got y=5-x and y=10-2x. Then I solved 5-x=10-2x and got x =5, giving y=0.
The answer given in my book also states that the point (3,4) is a point of intersection. How do I get this second point?
