Truthfully? It is an idiotic question. I dare you to define "most efficient".
OpenStudy (winsteria):
Well, I still need help with it.

OpenStudy (welshfella):
well it is easier to substutute in an expression that is not a fraction
so I think we can rule out options 2 and 4
OpenStudy (welshfella):
which one do you think is easier to plug into the first equation
1 or 3?
OpenStudy (winsteria):
1st one.
OpenStudy (rose4825):
I believe it would be the first one, because then you would be able to plug in the x-value into the other equation.
OpenStudy (welshfella):
you have 4y in the 3rd one and 2y in the first equation in the question .....

If you were my child in a high school algebra class, your teacher would hear from me on this one! Very, very bad!! Horrible. I hope it's not in a book. Is it? If it is, tell me the author, I'll write them a letter. Horrid, nasty, disgusting problem.
