Which method should be used to solve the system? Explain your answer, including a description of the first step.-8x2 + 10y2 = 36x - 9y =-1
What will be an ideal response?
Substitution should be used, because using elimination would mean introducing an xy term into the second equation unnecessarily. The second equation should be solved for x.
