Given the system of equations presented here: 2x + 4y = 14 4x + y = 20 Which of the following actions creates an equivalent system such that, when combined with the other equation, one of the variables is eliminated? (5 points)

Multiply the second equation by −4 to get −16x − 4y = −80
Multiply the second equation by −1 to get −4x − y = −20
Multiply the first equation by 2 to get 4x + 8y = 28
Multiply the first equation by −1 to get −2x − 4y = −14

Answer 1

I believe it would be "Multiply the second equation by −4 to get −16x − 4y = −80" as that would cancel out the variable y.

Answer 2

I say it is A. thanks
