Answer 8

Truthfully? It is an idiotic question. I dare you to define "most efficient".

Answer 9

Well, I still need help with it.

Answer 10

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

Answer 11

which one do you think is easier to plug into the first equation
1 or 3?

Answer 12

1st one.

Answer 13

I believe it would be the first one, because then you would be able to plug in the x-value into the other equation.

Answer 14

you have 4y in the 3rd one and 2y in the first equation in the question .....

Answer 16

Right i agree The first one.

Answer 17

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.
