This is meant to determine which of the three ways we are studying to use when solving a system involving at least one nonlinear equation.










Do the two equations have the exact same powers of either x or y?
 YES

Use elimination!

 
 
 
NO









Does ONE of the equations have just x or just y (no squares) in it?
 YES

Use substitution!

 
 
 
NO









Graph them, find the intersections
Remember to use both + and  if you have a root!
