Which method should be used to solve the system? Explain your answer, including a description of the first step.x2 + y2 =1610x - 5y =10
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 or y.
