x+y=2

x-y=4

x+y=5

Kelly, generally these equations have to be paired to answer these questions.  For example, you can answer whether the system of equations

x+y=2 and x-y=4 are Consistent Independent, Consistent dependent or inconsistent.  But you cannot evaluate this one equation at a time.

There is a good article on what these terms mean at

I hope this helps.  John
