don't know how to proceed with the following problems. this whole section is giving me fits. Thanks in advance! 1st system x^2 - y^2 =5 x^2 + 4y^2 = 25 2nd system x^2 - y^2 = 20 x^2 - 9y = 0 3rd system x^2 + y^2 = 10 x^2 + y^2 - 4y + 2 = 0

(2) [snip] From (1): x^2 = 5 + y^2. Substitute into (2) and solve for y^2 and hence y. Use your values of y to solve for x.
